+Branch a New Release
+====================
+
+This section covers how to start a new ``release`` branch for a major or
+minor version bump (patch releases remain on their existing branch).
+
+In the following we use the placeholder ``$ver`` to represent the
+version number of the new release with the form ``$major.$minor``,
+and ``$prev`` to represent the version number of the prior release.
+
+Review Prior Release
+--------------------
+
+Review the history around the prior release branch:
+
+.. code-block:: shell
+
+  git log --graph --boundary \
+   ^$(git rev-list --grep="Merge topic 'doc-.*-relnotes'" -n 1 master)~1 \
+   $(git rev-list --grep="Begin post-.* development" -n 1 master) \
+   $(git tag --list *-rc1| tail -1)
+
+Consolidate Release Notes
+-------------------------
+
+Starting from a clean work tree on ``master``, create a topic branch to
+use for consolidating the release notes:
+
+.. code-block:: shell
+
+  git checkout -b doc-$ver-relnotes
+
+Run the `consolidate-relnotes.bash`_ script:
+
+.. code-block:: shell
+
+  Utilities/Release/consolidate-relnotes.bash $ver $prev
+
+.. _`consolidate-relnotes.bash`: ../../Utilities/Release/consolidate-relnotes.bash
+
+This moves notes from the ``Help/release/dev/*.rst`` files into a versioned
+``Help/release/$ver.rst`` file and updates ``Help/release/index.rst`` to
+link to the new document.  Commit the changes with a message such as::
+
+  Help: Consolidate $ver release notes
+
+  Run the `Utilities/Release/consolidate-relnotes.bash` script to move
+  notes from `Help/release/dev/*` into `Help/release/$ver.rst`.
+
+Manually edit ``Help/release/$ver.rst`` to add section headers, organize
+the notes, and revise wording.  Then commit with a message such as::
+
+  Help: Organize and revise $ver release notes
+
+  Add section headers similar to the $prev release notes and move each
+  individual bullet into an appropriate section.  Revise a few bullets.
+
+Open a merge request with the ``doc-$ver-relnotes`` branch for review
+and integration.  Further steps may proceed after this has been merged
+to ``master``.
+
+Update 'release' Branch
+-----------------------
+
+Starting from a clean work tree on ``master``, create a new ``release-$ver``
+branch locally:
+
+.. code-block:: shell
+
+  git checkout -b release-$ver origin/master
+
+Remove the development branch release note infrastructure:
+
+.. code-block:: shell
+
+  git rm Help/release/dev/0-sample-topic.rst
+  sed -i '/^\.\. include:: dev.txt/ {N;d}' Help/release/index.rst
+
+Commit with a message such as::

+CMake Review Process
+********************
+
+The following documents the process for reviewing and integrating changes.
+See `CONTRIBUTING.rst`_ for instructions to contribute changes.
+See documentation on `CMake Development`_ for more information.
+
+.. _`CONTRIBUTING.rst`: ../../CONTRIBUTING.rst
+.. _`CMake Development`: README.rst
+
+.. contents:: The review process consists of the following steps:
+
+Merge Request
+=============
+
+A user initiates the review process for a change by pushing a *topic
+branch* to his or her own fork of the `CMake Repository`_ on GitLab and
+creating a *merge request* ("MR").  The new MR will appear on the
+`CMake Merge Requests Page`_.  The rest of the review and integration
+process is managed by the merge request page for the change.
+
+During the review process, the MR submitter should address review comments
+or test failures by updating the MR with a (force-)push of the topic
+branch.  The update initiates a new round of review.
+
+We recommend that users enable the "Remove source branch when merge
+request is accepted" option when creating the MR or by editing it.
+This will cause the MR topic branch to be automatically removed from
+the user's fork during the `Merge`_ step.
+
+.. _`CMake Merge Requests Page`: https://gitlab.kitware.com/cmake/cmake/merge_requests
+.. _`CMake Repository`: https://gitlab.kitware.com/cmake/cmake
+
+Workflow Status
+---------------
+
+`CMake GitLab Project Developers`_ may set one of the following labels
+in GitLab to track the state of a MR:
+
+* ``workflow:wip`` indicates that the MR needs additional updates from
+  the MR submitter before further review.  Use this label after making
+  comments that require such updates.
+
+* ``workflow:in-review`` indicates that the MR awaits feedback from a
+  human reviewer or from `Topic Testing`_.  Use this label after making
+  comments requesting such feedback.
+
+* ``workflow:nightly-testing`` indicates that the MR awaits results
+  of `Integration Testing`_.  Use this label after making comments
+  requesting such staging.
+
+* ``workflow:expired`` indicates that the MR has been closed due
+  to a period of inactivity.  See the `Expire`_ step.  Use this label
+  after closing a MR for this reason.
+
+The workflow status labels are intended to be mutually exclusive,
+so please remove any existing workflow label when adding one.
+
+.. _`CMake GitLab Project Developers`: https://gitlab.kitware.com/cmake/cmake/settings/members
+
+Robot Review
+============
+
+The "Kitware Robot" (``@kwrobot``) automatically performs basic checks on
+the commits proposed in a MR.  If all is well the robot silently reports
+a successful "build" status to GitLab.  Otherwise the robot posts a comment
+with its diagnostics.  **A topic may not be merged until the automatic
+review succeeds.**
+
+Note that the MR submitter is expected to address the robot's comments by
+*rewriting* the commits named by the robot's diagnostics (e.g., via
+``git rebase -i``). This is because the robot checks each commit individually,
+not the topic as a whole. This is done in order to ensure that commits in the
+middle of a topic do not, for example, add a giant file which is then later
+removed in the topic.
+
+Automatic Check
+---------------
+
+The automatic check is repeated whenever the topic branch is updated.
+One may explicitly request a re-check by adding a comment with the
+following command among the `comment trailing lines`_::
+
+  Do: check
+
+``@kwrobot`` will add an award emoji to the comment to indicate that it
+was processed and also run its checks again.
+
+Automatic Format
+----------------
+
+The automatic check will reject commits introducing source code not
+formatted according to ``clang-format``.  One may ask the robot to
+automatically rewrite the MR topic branch with expected formatting
+by adding a comment with the following command among the
+`comment trailing lines`_::
+
+  Do: reformat
+
+``@kwrobot`` will add an award emoji to the comment to indicate that it
+was processed and also rewrite the MR topic branch and force-push an
+updated version with every commit formatted as expected by the check.
+
+Human Review
+============
+
+Anyone is welcome to review merge requests and make comments!
+
+Please make comments directly on the MR page Discussion and Changes tabs
+and not on individual commits.  Comments on a commit may disappear
+from the MR page if the commit is rewritten in response.
+
+Reviewers may add comments providing feedback or to acknowledge their
+approval.  Lines of specific forms will be extracted during the `merge`_
+step and included as trailing lines of the generated merge commit message.
+Each review comment consists of up to two parts which must be specified
+in the following order: `comment body`_, then `comment trailing lines`_.
+Each part is optional, but they must be specified in this order.
+
+Comment Body
+------------
+
+The body of a comment may be free-form `GitLab Flavored Markdown`_.
+See GitLab documentation on `Special GitLab References`_ to add links to
+things like issues, commits, or other merge requests (even across projects).
+
+Additionally, a line in the comment body may start with one of the
+following votes:
+
+* ``-1`` or ``:-1:`` indicates "the change is not ready for integration".
+
+* ``+1`` or ``:+1:`` indicates "I like the change".
+  This adds an ``Acked-by:`` trailer to the `merge`_ commit message.
+
+* ``+2`` indicates "the change is ready for integration".
+  This adds a ``Reviewed-by:`` trailer to the `merge`_ commit message.
+
+* ``+3`` indicates "I have tested the change and verified it works".
+  This adds a ``Tested-by:`` trailer to the `merge`_ commit message.
+
+.. _`GitLab Flavored Markdown`: https://gitlab.kitware.com/help/user/markdown.md
+.. _`Special GitLab References`: https://gitlab.kitware.com/help/user/markdown.md#special-gitlab-references
+
+Comment Trailing Lines
+----------------------
+
+Zero or more *trailing* lines in the last section of a comment may appear
+with the form ``Key: Value``.  The first such line should be separated
+from a preceding `comment body`_ by a blank line.  Any key-value pair(s)
+may be specified for human reference.  A few specific keys have meaning to
+``@kwrobot`` as follows.
+
+Comment Trailer Votes
+^^^^^^^^^^^^^^^^^^^^^
+
+Among the `comment trailing lines`_ one may cast a vote using one of the
+following pairs followed by nothing but whitespace before the end of the line:
+
+* ``Rejected-by: me`` indicates "the change is not ready for integration".
+* ``Acked-by: me`` indicates "I like the change".
+  This adds an ``Acked-by:`` trailer to the `merge`_ commit message.
+* ``Reviewed-by: me`` indicates "the change is ready for integration".
+  This adds a ``Reviewed-by:`` trailer to the `merge`_ commit message.
+* ``Tested-by: me`` indicates "I have tested the change and verified it works".
+  This adds a ``Tested-by:`` trailer to the `merge`_ commit message.
+
+Each ``me`` reference may instead be an ``@username`` reference or a full
+``Real Name <user@domain>`` reference to credit someone else for performing
+the review.  References to ``me`` and ``@username`` will automatically be
+transformed into a real name and email address according to the user's
+GitLab account profile.
+
+Comment Trailer Commands
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+Among the `comment trailing lines`_ authorized users may issue special
+commands to ``@kwrobot`` using the form ``Do: ...``:
+
+* ``Do: check`` explicitly re-runs the robot `Automatic Check`_.
+* ``Do: reformat`` rewrites the MR topic for `Automatic Format`_.
+* ``Do: test`` submits the MR for `Topic Testing`_.
+* ``Do: stage`` submits the MR for `Integration Testing`_.
+* ``Do: merge`` submits the MR for `Merge`_.
+
+See the corresponding sections for details on permissions and options
+for each command.
+
+Topic Testing
+=============
+
+CMake has a `buildbot`_ instance watching for merge requests to test.
+`CMake GitLab Project Developers`_ may activate buildbot on a MR by
+adding a comment with a command among the `comment trailing lines`_::
+
+  Do: test
+
+``@kwrobot`` will add an award emoji to the comment to indicate that it
+was processed and also inform buildbot about the request.  The buildbot
+user (``@buildbot``) will schedule builds and respond with a comment
+linking to the `CMake CDash Page`_ with a filter for results associated
+with the topic test request.  If the MR topic branch is updated by a
+push a new ``Do: test`` command is needed to activate testing again.
+
+The ``Do: test`` command accepts the following arguments:
+
+* ``--stop``: clear the list of commands for the merge request
+* ``--clear``: clear previous commands before adding this command
+* ``--regex-include <arg>`` or ``-i <arg>``: only build on builders
+  matching ``<arg>`` (a Python regular expression)
+* ``--regex-exclude <arg>`` or ``-e <arg>``: exclude builds on builders
+  matching ``<arg>`` (a Python regular expression)
+
+Builder names follow the pattern ``project-host-os-buildtype-generator``:
+
+* ``project``: always ``cmake`` for CMake builds
+* ``host``: the buildbot host
+* ``os``: one of ``windows``, ``osx``, or ``linux``
+* ``buildtype``: ``release`` or ``debug``
+* ``generator``: ``ninja``, ``makefiles``, ``vs<year>``,
+  or ``lint-iwyu-tidy``
+
+The special ``lint-<tools>`` generator name is a builder that builds
+CMake using lint tools but does not run the test suite (so the actual
+generator does not matter).
+
+.. _`buildbot`: http://buildbot.net
+.. _`CMake CDash Page`: https://open.cdash.org/index.php?project=CMake
+
+Integration Testing
+===================
+
+The above `topic testing`_ tests the MR topic independent of other
+merge requests and on only a few key platforms and configurations.
+The `CMake Testing Process`_ also has a large number of machines
+provided by Kitware and generous volunteers that cover nearly all
+supported platforms, generators, and configurations.  In order to
+avoid overwhelming these resources, they do not test every MR
+individually.  Instead, these machines follow an *integration branch*,
+run tests on a nightly basis (or continuously during the day), and
+post to the `CMake CDash Page`_.  Some follow ``master``.  Most follow
+a special integration branch, the *topic stage*.
+
+The topic stage is a special branch maintained by the "Kitware Robot"
+(``@kwrobot``).  It consists of the head of the MR target integration
+branch (e.g. ``master``) branch followed by a sequence of merges each
+integrating changes from an open MR that has been staged for integration
+testing.  Each time the target integration branch is updated the stage
+is rebuilt automatically by merging the staged MR topics again.
+
+`CMake GitLab Project Developers`_ may stage a MR for integration testing
+by adding a comment with a command among the `comment trailing lines`_::
+
+  Do: stage
+
+``@kwrobot`` will add an award emoji to the comment to indicate that it
+was processed and also attempt to add the MR topic branch to the topic
+stage.  If the MR cannot be added (e.g. due to conflicts) the robot will
+post a comment explaining what went wrong.
+
+Once a MR has been added to the topic stage it will remain on the stage
+until one of the following occurs:
+
+* The MR topic branch is updated by a push.
+
+* The MR target integration branch (e.g. ``master``) branch is updated
+  and the MR cannot be merged into the topic stage again due to conflicts.
+
+* A developer or the submitter posts an explicit ``Do: unstage`` command.
+  This is useful to remove a MR from the topic stage when one is not ready
+  to push an update to the MR topic branch.  It is unnecessary to explicitly
+  unstage just before or after pushing an update because the push will cause
+  the MR to be unstaged automatically.
+
+* The MR is closed.
+
+* The MR is merged.
+
+Once a MR has been removed from the topic stage a new ``Do: stage``
+command is needed to stage it again.
+
+.. _`CMake Testing Process`: testing.rst
+
+Resolve
+=======
+
+A MR may be resolved in one of the following ways.
+
+Merge
+-----
+
+Once review has concluded that the MR topic is ready for integration,
+`CMake GitLab Project Masters`_ may merge the topic by adding a comment
+with a command among the `comment trailing lines`_::
+
+  Do: merge
+
+``@kwrobot`` will add an award emoji to the comment to indicate that it
+was processed and also attempt to merge the MR topic branch to the MR
+target integration branch (e.g. ``master``).  If the MR cannot be merged
+(e.g. due to conflicts) the robot will post a comment explaining what
+went wrong.  If the MR is merged the robot will also remove the source
+branch from the user's fork if the corresponding MR option was checked.
+
+The robot automatically constructs a merge commit message of the following
+form::
+
+  Merge topic 'mr-topic-branch-name'
+
+  00000000 commit message subject line (one line per commit)
+
+  Acked-by: Kitware Robot <kwrobot@kitware.com>
+  Merge-request: !0000
+
+Mention of the commit short sha1s and MR number helps GitLab link the
+commits back to the merge request and indicates when they were merged.
+The ``Acked-by:`` trailer shown indicates that `Robot Review`_ passed.
+Additional ``Acked-by:``, ``Reviewed-by:``, and similar trailers may be
+collected from `Human Review`_ comments that have been made since the
+last time the MR topic branch was updated with a push.
+
+The ``Do: merge`` command accepts the following arguments:
+
+* ``-t <topic>``: substitute ``<topic>`` for the name of the MR topic
+  branch in the constructed merge commit message.
+
+Additionally, ``Do: merge`` extracts configuration from trailing lines
+in the MR description:
+
+* ``Topic-rename: <topic>``: substitute ``<topic>`` for the name of
+  the MR topic branch in the constructed merge commit message.
+  The ``-t`` option overrides this.
+
+.. _`CMake GitLab Project Masters`: https://gitlab.kitware.com/cmake/cmake/settings/members
+
+Close
+-----
+
+If review has concluded that the MR should not be integrated then it
+may be closed through GitLab.
+
+Expire
+------
+
+If progress on a MR has stalled for a while, it may be closed with a
+``workflow:expired`` label and a comment indicating that the MR has
+been closed due to inactivity.
+
+Contributors are welcome to re-open an expired MR when they are ready
+to continue work.  Please re-open *before* pushing an update to the
+MR topic branch to ensure GitLab will still act on the association.

+CMake Source Code Guide
+***********************
+
+The following is a guide to the CMake source code for developers.
+See documentation on `CMake Development`_ for more information.
+
+.. _`CMake Development`: README.rst
+
+C++ Code Style
+==============
+
+We use `clang-format`_ version **3.8** to define our style for C++ code in
+the CMake source tree.  See the `.clang-format`_ configuration file for our
+style settings.  Use the `Utilities/Scripts/clang-format.bash`_ script to
+format source code.  It automatically runs ``clang-format`` on the set of
+source files for which we enforce style.  The script also has options to
+format only a subset of files, such as those that are locally modified.

+.. _`clang-format`: http://clang.llvm.org/docs/ClangFormat.html
+.. _`.clang-format`: ../../.clang-format
+.. _`Utilities/Scripts/clang-format.bash`: ../../Utilities/Scripts/clang-format.bash
+
+C++ Subset Permitted
+====================
+
+CMake supports compiling as C++98 in addition to C++11 and C++14.
+In order to support building on older toolchains some constructs
+need to be handled with care:
+
+* Use ``CM_AUTO_PTR`` instead of ``std::auto_ptr``.
+
+  The ``std::auto_ptr`` template is deprecated in C++11.  We want to use it
+  so we can build on C++98 compilers but we do not want to turn off compiler
+  warnings about deprecated interfaces in general.  Use the ``CM_AUTO_PTR``
+  macro instead.
+
+* Use ``CM_EQ_DELETE;`` instead of ``= delete;``.
+
+  Defining functions as *deleted* is not supported in C++98.  Using
+  ``CM_EQ_DELETE`` will delete the functions if the compiler supports it and
+  give them no implementation otherwise.  Calling such a function will lead
+  to compiler errors if the compiler supports *deleted* functions and linker
+  errors otherwise.
+
+* Use ``CM_DISABLE_COPY(Class)`` to mark classes as non-copyable.
+
+  The ``CM_DISABLE_COPY`` macro should be used in the private section of a
+  class to make sure that attempts to copy or assign an instance of the class
+  lead to compiler errors even if the compiler does not support *deleted*
+  functions.  As a guideline, all polymorphic classes should be made
+  non-copyable in order to avoid slicing.  Classes that are composed of or
+  derived from non-copyable classes must also be made non-copyable explicitly
+  with ``CM_DISABLE_COPY``.
+
+* Use ``size_t`` instead of ``std::size_t``.
+
+  Various implementations have differing implementation of ``size_t``.
+  When assigning the result of ``.size()`` on a container for example,
+  the result should be assigned to ``size_t`` not to ``std::size_t``,
+  ``unsigned int`` or similar types.

+
+CMake Dashboard Scripts
+=======================
+
+The *integration testing* step of the `CMake Review Process`_ uses a set of
+testing machines that follow an integration branch on their own schedule to
+drive testing and submit results to the `CMake CDash Page`_.  Anyone is
+welcome to provide testing machines in order to help keep support for their
+platforms working.
+
+The `CMake Dashboard Scripts Repository`_ provides CTest scripts to drive
+nightly, continous, and experimental testing of CMake.  Use the following
+commands to set up a new integration testing client:
+
+.. code-block:: console
+
+  $ mkdir -p ~/Dashboards
+  $ cd ~/Dashboards
+  $ git clone https://gitlab.kitware.com/cmake/dashboard-scripts.git CMakeScripts
+  $ cd CMakeScripts
+
+The ``cmake_common.cmake`` script contains comments at the top with
+instructions to set up a testing client.  As it instructs, create a
+CTest script with local settings and include ``cmake_common.cmake``.

+Nightly Start Time
+------------------
+
+The ``cmake_common.cmake`` script expects its includer to be run from a
+nightly scheduled task (cron job).  Schedule such tasks for sometime after
+``1:00am UTC``, the time at which our nightly testing branches fast-forward.

 source tree itself, and by those authoring externally-maintained modules.
 
-
-Permitted C++ Subset
-====================
-
-CMake is required to build with ancient C++ compilers and standard library
-implementations.  Some common C++ constructs may not be used in CMake in order
-to build with such toolchains.
-
-std::auto_ptr
--------------
-
-The ``std::auto_ptr`` template is deprecated in C++11.  We want to use it
-so we can build on C++98 compilers but we do not want to turn off compiler
-warnings about deprecated interfaces in general.  Use the ``CM_AUTO_PTR``
-macro instead.
-
-size_t
-------
-
-Various implementations have differing implementation of ``size_t``.  When
-assigning the result of ``.size()`` on a container for example, the result
-should be assigned to ``size_t`` not to ``std::size_t``, ``unsigned int`` or
-similar types.

+``RPATH`` settings on macOS do not affect ``install_name``.

+* :prop_tgt:`SKIP_BUILD_RPATH` target property
+* :variable:`CMAKE_SKIP_RPATH` variable
+* :variable:`CMAKE_SKIP_INSTALL_RPATH` variable
+
+Previously, setting :prop_tgt:`BUILD_WITH_INSTALL_RPATH` had the effect of
+setting both the ``install_name`` of a target to :prop_tgt:`INSTALL_NAME_DIR`
+and the ``RPATH`` to :prop_tgt:`INSTALL_RPATH`.  In CMake 3.9, it only affects
+setting of ``RPATH``.  However, if one wants :prop_tgt:`INSTALL_NAME_DIR` to
+apply to the target in the build tree, one may set
+:prop_tgt:`BUILD_WITH_INSTALL_NAME_DIR`.
+
+If :prop_tgt:`SKIP_BUILD_RPATH`, :variable:`CMAKE_SKIP_RPATH` or
+:variable:`CMAKE_SKIP_INSTALL_RPATH` were used to strip the directory portion
+of the ``install_name`` of a target, one may set ``INSTALL_NAME_DIR=""``
+instead.
+
+The ``OLD`` behavior of this policy is to use the ``RPATH`` settings for
+``install_name`` on macOS.  The ``NEW`` behavior of this policy is to ignore
+the ``RPATH`` settings for ``install_name`` on macOS.
+

+
+:prop_tgt:`INTERPROCEDURAL_OPTIMIZATION` is enforced when enabled.
+
+CMake 3.9 and newer prefer to add IPO flags whenever the
+:prop_tgt:`INTERPROCEDURAL_OPTIMIZATION` target property is enabled and
+produce an error if flags are not known to CMake for the current compiler.
+Since a given compiler may not support IPO flags in all environments in which
+it is used, it is now the project's responsibility to use the
+:module:`CheckIPOSupported` module to check for support before enabling the
+:prop_tgt:`INTERPROCEDURAL_OPTIMIZATION` target property.  This approach
+allows a project to conditionally activate IPO when supported.  It also
+allows an end user to set the :variable:`CMAKE_INTERPROCEDURAL_OPTIMIZATION`
+variable in an environment known to support IPO even if the project does
+not enable the property.
+
+Since CMake 3.8 and lower only honored :prop_tgt:`INTERPROCEDURAL_OPTIMIZATION`
+for the Intel compiler on Linux, some projects may unconditionally enable the
+target property.  Policy ``CMP0069`` provides compatibility with such projects.
+
+This policy takes effect whenever the IPO property is enabled.  The ``OLD``
+behavior for this policy is to add IPO flags only for Intel compiler on Linux.
+The ``NEW`` behavior for this policy is to add IPO flags for the current
+compiler or produce an error if CMake does not know the flags.
+
+This policy was introduced in CMake version 3.9.  CMake version
+|release| warns when the policy is not set and uses ``OLD`` behavior.

+Examples
+^^^^^^^^
+
+Behave like CMake 3.8 and do not apply any IPO flags except for Intel compiler
+on Linux:
+
+.. code-block:: cmake
+
+  cmake_minimum_required(VERSION 3.8)
+  project(foo)
+
+  # ...
+
+  set_property(TARGET ... PROPERTY INTERPROCEDURAL_OPTIMIZATION TRUE)
+
+Use the :module:`CheckIPOSupported` module to detect whether IPO is
+supported by the current compiler, environment, and CMake version.
+Produce a fatal error if support is not available:
+
+.. code-block:: cmake
+
+  cmake_minimum_required(VERSION 3.9) # CMP0069 NEW
+  project(foo)
+
+  include(CheckIPOSupport)
+  check_ipo_support()
+
+  # ...
+
+  set_property(TARGET ... PROPERTY INTERPROCEDURAL_OPTIMIZATION TRUE)
+
+Apply IPO flags only if compiler supports it:
+
+.. code-block:: cmake
+
+  cmake_minimum_required(VERSION 3.9) # CMP0069 NEW
+  project(foo)
+
+  include(CheckIPOSupport)
+
+  # ...
+
+  check_ipo_support(RESULT result)
+  if(result)
+    set_property(TARGET ... PROPERTY INTERPROCEDURAL_OPTIMIZATION TRUE)
+  endif()
+
+Apply IPO flags without any checks.  This may lead to build errors if IPO
+is not supported by the compiler in the current environment.  Produce an
+error if CMake does not know IPO flags for the current compiler:
+
+.. code-block:: cmake
+
+  cmake_minimum_required(VERSION 3.9) # CMP0069 NEW
+  project(foo)

+AUTOMOC_DEPEND_FILTERS

+source code as additional dependencies for the ``moc`` file.
+
+This property is only used if the :prop_tgt:`AUTOMOC` property is ``ON``

+
+Filters are defined as ``KEYWORD;REGULAR_EXPRESSION`` pairs. First the file

+names are extracted by successively searching for ``REGULAR_EXPRESSION`` and
+taking the first match group.
+
+Consider a filter extracts the file name ``DEP`` from the content of a file
+``FOO``. If ``DEP`` changes, then the ``moc`` file for ``FOO`` gets rebuilt.
+The file ``DEP`` is searched for first in the vicinity
+of ``FOO`` and afterwards in the target's :prop_tgt:`INCLUDE_DIRECTORIES`.

+CMake 3.9 Release Notes
+***********************
+
+.. only:: html
+
+  .. contents::
+
+Changes made since CMake 3.8 include the following.
+
+New Features
+============
+
+Languages
+---------
+
+* ``CUDA`` is now supported by the :ref:`Visual Studio Generators`
+  for VS 2010 and above.  This complements the existing support by the
+  :ref:`Makefile Generators` and the :generator:`Ninja` generator.
+  CUDA 8.0.61 or higher is recommended due to known bugs in the VS
+  integration by earlier versions.
+
+* CMake is now aware of the :prop_tgt:`C++ standards <CXX_STANDARD>` and
+  :prop_tgt:`C standards <C_STANDARD>` and their associated meta-features for
+  the following :variable:`compiler ids <CMAKE_<LANG>_COMPILER_ID>`: ``Cray``,
+  ``PGI``, and ``XL``.
+
+Generators
+----------
+
+* :ref:`Visual Studio Generators` for VS 2010 and above learned to support
+  the ``ASM_NASM`` language when ``nasm`` is installed.
+
+* The :generator:`Xcode` generator learned to create Xcode schema files.
+  This is an experimental feature and can be activated by setting the
+  :variable:`CMAKE_XCODE_GENERATE_SCHEME` variable to a ``TRUE`` value.
+
+* The :generator:`Xcode` generator now supports Xcode 9.
+
+Commands
+--------
+
+* The :command:`add_library` command ``IMPORTED`` option learned to support
+  :ref:`Object Libraries`.
+
+* All ``find_`` commands now have a ``PACKAGE_ROOT`` search path group that
+  is first in the search heuristics.  If a ``find_`` command is called from
+  inside a find module, then the CMake variable and environment variable named
+  ``<PackageName>_ROOT`` are used as prefixes and are the first set of paths
+  to be searched.
+
+* The :command:`find_library` command learned to search ``libx32`` paths
+  when the build targets the ``x32`` ABI.  See the
+  :prop_gbl:`FIND_LIBRARY_USE_LIBX32_PATHS` global property.
+
+* The :command:`include_external_msproject` command learned to use
+  the :prop_tgt:`MAP_IMPORTED_CONFIG_<CONFIG>` target property
+  to map current configurations to the external configurations.
+
+* The :command:`install(TARGETS)` command learned a new ``OBJECTS`` option to
+  specify where to install :ref:`Object Libraries`.
+
+* The :command:`install(EXPORT)` command learned how to export
+  :ref:`Object Libraries`.
+
+* The :command:`project` command learned an optional ``DESCRIPTION``
+  parameter to set the :variable:`PROJECT_DESCRIPTION` variable.
+
+* The :command:`separate_arguments` command gained a ``NATIVE_COMMAND`` mode
+  that performs argument separation depending on the host operating system.
+
+Variables
+---------
+
+* A :variable:`CMAKE_ANDROID_NDK_DEPRECATED_HEADERS` variable was added
+  for use when :ref:`Cross Compiling for Android with the NDK` to request
+  use of the deprecated headers even when unified headers are available.
+  The default is now to use unified headers if available.
+
+* A :variable:`CMAKE_AUTOMOC_DEPEND_FILTERS` variable was introduced to
+  allow :variable:`CMAKE_AUTOMOC` to extract additional dependency file names
+  for ``moc`` from the contents of source files.
+
+* A :variable:`CMAKE_AUTOUIC_SEARCH_PATHS` variable was introduced to
+  allow :variable:`CMAKE_AUTOUIC` to search for ``foo.ui`` in more
+  places than the vicinity of the file including ``ui_foo.h``.
+
+* A :variable:`CMAKE_FIND_LIBRARY_CUSTOM_LIB_SUFFIX` variable was added to
+  tell the :command:`find_library` command to search in a ``lib<suffix>``
+  directory before each ``lib`` directory that would normally be searched.
+
+* A :variable:`CMAKE_INTERPROCEDURAL_OPTIMIZATION` variable was added to
+  initialize the :prop_tgt:`INTERPROCEDURAL_OPTIMIZATION` property on all
+  targets.
+
+* A :variable:`CMAKE_<LANG>_COMPILER_AR` variable was added to hold
+  the path to the GCC/Clang wrapper of ``ar``.
+
+* A :variable:`CMAKE_<LANG>_COMPILER_RANLIB` variable was added to hold
+  the path to the GCC/Clang wrapper of ``ranlib``.
+
+* The :variable:`CMAKE_SYSROOT_COMPILE` and :variable:`CMAKE_SYSROOT_LINK`
+  variables were added to use separate sysroots for compiling and linking.
+
+Properties
+----------
+
+* A new :prop_tgt:`AUTOGEN_BUILD_DIR` target property was introduced to set
+  a custom output directory for :prop_tgt:`AUTOMOC`, :prop_tgt:`AUTOUIC`,
+  and :prop_tgt:`AUTORCC`.
+
+* A new :prop_tgt:`AUTOMOC_DEPEND_FILTERS` target property was introduced to
+  allow :prop_tgt:`AUTOMOC` to extract additional dependency file names
+  for ``moc`` from the contents of source files.
+
+* A new :prop_tgt:`AUTOUIC_SEARCH_PATHS` target property was introduced to
+  allow :prop_tgt:`AUTOUIC` to search for ``foo.ui`` in more
+  places than the vicinity of the file including ``ui_foo.h``.
+
+* Global properties :prop_gbl:`AUTOGEN_SOURCE_GROUP`,
+  :prop_gbl:`AUTOMOC_SOURCE_GROUP` and
+  :prop_gbl:`AUTORCC_SOURCE_GROUP` were
+  introduced to allow files generated by :prop_tgt:`AUTOMOC` or
+  :prop_tgt:`AUTORCC` to be placed in a :command:`source_group`.
+
+* A :prop_tgt:`BUILD_WITH_INSTALL_NAME_DIR` target property and corresponding
+  :variable:`CMAKE_BUILD_WITH_INSTALL_NAME_DIR` variable were added to
+  control whether to use the :prop_tgt:`INSTALL_NAME_DIR` target property
+  value for binaries in the build tree.  This is for macOS ``install_name``
+  as :prop_tgt:`BUILD_WITH_INSTALL_RPATH` is for ``RPATH``.
+
+* A :prop_tgt:`CUDA_PTX_COMPILATION` target property was added to
+  :ref:`Object Libraries` to support compiling to ``.ptx`` files
+  instead of host object files.
+
+* A :prop_gbl:`GENERATOR_IS_MULTI_CONFIG` global property was
+  added to determine whether the current generator is a multi-configuration
+  generator (such as :ref:`Visual Studio Generators` or :generator:`Xcode`).
+
+* The :prop_tgt:`INTERPROCEDURAL_OPTIMIZATION` target property is now enforced
+  when enabled.  CMake will add IPO flags unconditionally or produce an error
+  if it does not know the flags for the current compiler.  The project is now
+  responsible to use the :module:`CheckIPOSupported` module to check for IPO
+  support before enabling the target property.  See policy :policy:`CMP0069`.
+
+* The :prop_tgt:`WINDOWS_EXPORT_ALL_SYMBOLS` target property may now
+  be used in combination with explicit ``.def`` files in order to
+  export all symbols from the object files within a target plus
+  an explicit list of symbols that the linker finds in dependencies
+  (e.g. ``msvcrt.lib``).
+
+Modules
+-------
+
+* A :module:`CheckIPOSupported` module was added to help projects
+  check whether interprocedural optimization (IPO) is supported by
+  the current toolchain and CMake version.
+
+* The :module:`CMakeFindDependencyMacro` module ``find_dependency`` macro
+  now forwards all arguments to the underlying :command:`find_package`
+  call.  Existing uses will continue to function as before, but callers can
+  now access the full suite of arguments that ``find_package`` accepts.
+
+* The :module:`FeatureSummary` module :command:`feature_summary` command now
+  accepts the new ``DEFAULT_DESCRIPTION`` option that will print the default
+  title for the selected package type.
+
+* The :module:`FeatureSummary` module gained a new
+  :variable:`FeatureSummary_<TYPE>_DESCRIPTION` variable that can be defined
+  for each ``<TYPE>`` to replace the type name with the specified string
+  whenever the package type is used in an output string by the module.
+
+* The :module:`FindDoxygen` module learned to control Doxygen behavior using
+  CMake variables and generate documentation via the newly added
+  :command:`doxygen_add_docs` function. The Doxygen input file (``Doxyfile``)
+  is automatically generated and doxygen is run as part of a custom target.
+  Additional components can be specified to find optional tools: ``dot``,
+  ``mscgen`` and ``dia``.
+
+* The :module:`FindMPI` module now provides imported targets.
+
+* The :module:`FindProtobuf` module :command:`protobuf_generate_cpp`
+  command gained an ``EXPORT_MACRO`` option to specify the name of
+  a DLL export markup macro.
+
+* The :module:`FindProtobuf` module now supports usage of static libraries
+  for Unix via a new ``Protobuf_USE_STATIC_LIBS`` input variable.
+
+* The :module:`FindProtobuf` module now provides imported targets
+  when the libraries are found.
+
+* A new :module:`GoogleTest` module was added to provide the
+  :command:`gtest_add_tests` function independently of the :module:`FindGTest`
+  module. The function was also updated to support keyword arguments, with
+  functionality expanded to allow a test name prefix and suffix to be
+  specified, the dependency on the source files to be optional and the list of
+  discovered test cases to be returned to the caller.
+
+CTest
+-----
+
+* The :command:`ctest_submit` command gained a ``HTTPHEADER`` option
+  to specify custom headers to send during submission.
+
+* The :manual:`ctest(1)` executable gained new options which allow the
+  developer to disable automatically adding tests to the test set to satisfy
+  fixture dependencies. ``-FS`` prevents adding setup tests for fixtures
+  matching the provided regular expression, ``-FC`` prevents adding cleanup
+  tests for matching fixtures and ``-FA`` prevents adding any test for matching
+  fixtures.
+
+* A :prop_test:`DISABLED` test property was added to mark tests that
+  are configured but explicitly disabled so they do not run.
+
+CPack
+-----
+
+* The :module:`CPackArchive` module learned to modify the filename
+  per-component.  See the :variable:`CPACK_ARCHIVE_FILE_NAME` variable and
+  its per-component version :variable:`CPACK_ARCHIVE_<component>_FILE_NAME`.
+
+* The :module:`CPackComponent` module :command:`cpack_add_component` command
+  gained a new ``PLIST <filename>`` option to specify the ``pkgbuild``
+  ``--component-plist`` argument when using the
+  :module:`productbuild <CPackProductBuild>` generator.
+
+* The :module:`CPackIFW` module :command:`cpack_ifw_configure_component` and
+  :command:`cpack_ifw_configure_component_group` commands gained
+  internationalization support for ``DISPLAY_NAME`` and ``DESCRIPTION``
+  options.
+
+* The :module:`CPackIFW` module learned the new hint :variable:`CPACK_IFW_ROOT`
+  variable for finding the QtIFW tool suite installed in a non-standard place.
+
+* The :module:`CPackProductBuild` module gained a new
+  :variable:`CPACK_PRODUCTBUILD_RESOURCES_DIR` variable to
+  specify resources to be copied into the ``Resources``
+  directory.
+
+* The :module:`CPackRPM` module learned to modify the ``debuginfo`` package
+  name.  See the :variable:`CPACK_RPM_DEBUGINFO_FILE_NAME` variable.
+
+* The :module:`CPackWIX` module patching system now has the ability to set
+  additional attributes.  This can be done by specifying attributes with
+  the ``CPackWiXFragment`` XML tag after the ``Id`` attribute.
+  See the :variable:`CPACK_WIX_PATCH_FILE` variable.
+
+* The CPack WIX generator implemented a new
+  :variable:`CPACK_WIX_ROOT_FOLDER_ID` variable which allows
+  using a custom root folder ID instead of the default
+  ``ProgramFilesFolder`` / ``ProgramFiles64Folder``.
+
+Other
+-----
+
+* Interprocedural optimization (IPO) is now supported for GNU and Clang
+  compilers using link time optimization (LTO) flags.  See the
+  :prop_tgt:`INTERPROCEDURAL_OPTIMIZATION` target property and
+  :module:`CheckIPOSupported` module.
+
+* The ``TARGET_OBJECTS``
+  :manual:`generator expression <cmake-generator-expressions(7)>`
+  is now supported by the :command:`add_custom_command` and
+  :command:`file(GENERATE)` commands.
+
+* Two new informational generator expressions to retrieve Apple Bundle
+  directories have been added. The first one ``$<TARGET_BUNDLE_DIR:tgt>``
+  outputs the full path to the Bundle directory, the other one
+  ``$<TARGET_BUNDLE_CONTENT_DIR:tgt>`` outputs the full path to the
+  ``Contents`` directory of macOS Bundles and App Bundles. For all other
+  bundle types and SDKs it is identical with ``$<TARGET_BUNDLE_DIR:tgt>``.
+  The new expressions are helpful to query Bundle locations independent of
+  the different Bundle types and layouts on macOS and iOS.
+
+Deprecated and Removed Features
+===============================
+
+* An explicit deprecation diagnostic was added for policies ``CMP0036``
+  and below.  The :manual:`cmake-policies(7)` manual explains that the
+  OLD behaviors of all policies are deprecated and that projects should
+  always port to the NEW behaviors as soon as possible.
+
+* The :generator:`Visual Studio 8 2005` generator is now deprecated
+  and will be removed in a future version of CMake.
+
+* The :generator:`Visual Studio 7 .NET 2003` generator has been removed.
+
+* The :generator:`Xcode` generator dropped support for Xcode versions
+  older than 3.
+
+* The :module:`FindDoxygen` module has deprecated several variables.
+
+* The version of curl bundled with CMake no longer accepts URLs of the form
+  ``file://c:/...`` on Windows due to a change in upstream curl 7.52.  Use
+  the form ``file:///c:/...`` instead to work on all versions.
+
+Other Changes
+=============
+
+* When using :prop_tgt:`AUTOMOC`, CMake now scans for the presence of the
+  ``Q_PLUGIN_METADATA`` macro and reruns moc when the file from the
+  macro's ``FILE`` argument changes.
+
+* When :prop_tgt:`AUTOMOC` detects an include statement of the form
+  ``#include "moc_<basename>.cpp"`` the search for the respective header file
+  now looks in the :prop_tgt:`INCLUDE_DIRECTORIES` of the target as well.
+
+* When running tests, CTest learned to treat skipped tests (using the
+  :prop_test:`SKIP_RETURN_CODE` property) the same as tests with the new
+  :prop_test:`DISABLED` property. Due to this change, CTest will not indicate
+  failure when all tests are either skipped or pass.
+
+* The :generator:`Ninja` generator has loosened the dependencies of object
+  compilation.  Object compilation now depends only on custom targets
+  and custom commands associated with libraries on which the object's target
+  depends and no longer depends on the libraries themselves.  Source files
+  in dependent targets may now compile without waiting for their targets'
+  dependencies to link.
+
+* On macOS, the default application bundle ``Info.plist`` file now enables
+  Hi-DPI support.
+
+* On macOS, ``RPATH`` settings such as :prop_tgt:`BUILD_WITH_INSTALL_RPATH`
+  no longer affect the ``install_name`` field.  See policy :policy:`CMP0068`.
+
+* The :generator:`Visual Studio 14 2015` generator has been taught about
+  a change to the ``v140`` toolset made by a VS 2015 update.  VS changed
+  the set of values it understands for the ``GenerateDebugInformation``
+  linker setting that produces the ``-DEBUG`` linker flag variants.
