cmake_pkg_config(EXTRACT <package> [<version>] [...])
|
||||||
|
|
||||||
|
Introduction
|
||||||
|
^^^^^^^^^^^^
|
||||||
|
|
||||||
|
This command generates CMake variables and targets from pkg-config format
|
||||||
|
package files natively, without needing to invoke or even require the presence
|
||||||
|
of a pkg-config implementation. A ``<package>`` is either an absolute path to a
|
||||||
|
package file, or a package name to be searched for using the typical pkg-config
|
||||||
|
search patterns. The optional ``<version>`` string has the same format and
|
||||||
|
semantics as a pkg-config style version specifier, with the exception that if
|
||||||
|
no comparison operator is specified ``=`` is assumed.
|
||||||
|
|
||||||
|
.. _`common options`:
|
||||||
|
|
||||||
|
There are multiple signatures for this command, and some of the options are
|
||||||
|
common between them. They are:
|
||||||
|
|
||||||
|
``EXACT`` / ``QUIET`` / ``REQUIRED``
|
||||||
|
The ``EXACT`` option requests that the version string be matched exactly
|
||||||
|
(including empty string, if no version is provided), overriding the typical
|
||||||
|
pkg-config version comparison algorithm. This will ignore any comparison
|
||||||
|
operator attached to the version string.
|
||||||
|
|
||||||
|
The ``QUIET`` option disables informational messages, including those
|
||||||
|
indicating that the package cannot be found if it is not ``REQUIRED``. The
|
||||||
|
``REQUIRED`` option stops processing with an error message if the package
|
||||||
|
cannot be found.
|
||||||
|
|
||||||
|
``STRICTNESS <mode>``
|
||||||
|
Specify how strictly the contents of the package files will be verified during
|
||||||
|
parsing and resolution. An invalid file, under the provided strictness mode,
|
||||||
|
will cause the command to fail. Possible modes are:
|
||||||
|
|
||||||
|
* ``STRICT``: Closely mirrors the behavior of the original FDO pkg-config.
|
||||||
|
Variables and keywords must be unique. Variables must be defined before
|
||||||
|
they are used. The Name, Description, and Version keywords must be present.
|
||||||
|
The overall structure of the file must be valid and parsable.
|
||||||
|
|
||||||
|
* ``PERMISSIVE``: Closely mirrors the behavior of the pkgconf implementation.
|
||||||
|
Duplicate variables are overridden. Duplicate keywords are appended.
|
||||||
|
Undefined variables resolve to empty strings. The Name, Description, and
|
||||||
|
Version keywords must be present. The overall structure of the file must be
|
||||||
|
valid and parsable.
|
||||||
|
|
||||||
|
* ``BEST_EFFORT``: Same behavior as ``PERMISSIVE`` with regards to duplicate
|
||||||
|
or uninitialized variables and keywords, but will not fail under any
|
||||||
|
conditions. Package files which require BEST_EFFORT will fail validation
|
||||||
|
under all other major implementations and should be fixed.
|
||||||
|
|
||||||
|
The default strictness is ``PERMISSIVE``.
|
||||||
|
|
||||||
|
``ENV_MODE``
|
||||||
|
Specifies which environment variables will be queried when running a given
|
||||||
|
command. Possible modes are:
|
||||||
|
|
||||||
|
* ``FDO``: Queries only the original set of ``PKG_CONFIG_*`` environment
|
||||||
|
variables used by the freedesktop.org ``pkg-config`` implementation.
|
||||||
|
|
||||||
|
* ``PKGCONF``: Queries the more extensive set of environment variables used
|
||||||
|
by the ``pkgconf`` implementation.
|
||||||
|
|
||||||
|
* ``IGNORE``: Ignores the presence, absence, and value of environment
|
||||||
|
variables entirely. In all cases an environment variable would be queried
|
||||||
|
its treated as defined, but with a value of empty string for the purpose
|
||||||
|
of the operation. This does not modify the current environment. For boolean
|
||||||
|
environment variables, such as ``PKG_CONFIG_ALLOW_*``, this means they are
|
||||||
|
evaluated as truthy.
|
||||||
|
|
||||||
|
``PKG_CONFIG_SYSROOT_PATH`` is a minor exception. When ``ENV_MODE IGNORE``
|
||||||
|
is used, no root path prepending will occur by default and ``pc_sysrootdir``
|
||||||
|
remains defaulted to ``/``.
|
||||||
|
|
||||||
|
Target-generating subcommands always ignore flag-filtering environment
|
||||||
|
variables. The default environment mode is ``PKGCONF``.
|
||||||
|
|
||||||
|
``PC_LIBDIR <path>...``
|
||||||
|
Overrides the default search location for package files; also used to derive
|
||||||
|
the ``pc_path`` package variable.
|
||||||
|
|
||||||
|
When this option is not provided, the default library directory is the first
|
||||||
|
available of the following values:
|
||||||
|
|
||||||
|
#. ``CMAKE_PKG_CONFIG_PC_LIB_DIRS``
|
||||||
|
#. The ``PKG_CONFIG_LIBDIR`` environment variable
|
||||||
|
#. The output of ``pkg-config --variable pc_path pkg-config``
|
||||||
|
#. A platform-dependent default value
|
||||||
|
|
||||||
|
``PC_PATH <path>...``
|
||||||
|
Overrides the supplemental package file directories which will be prepended
|
||||||
|
to the search path; also used to derive the ``pc_path`` package variable.
|
||||||
|
|
||||||
|
When this option is not provided, the default paths are the first available of
|
||||||
|
the following values:
|
||||||
|
|
||||||
|
#. ``CMAKE_PKG_CONFIG_PC_PATH``
|
||||||
|
#. The ``PKG_CONFIG_PATH`` environment variable
|
||||||
|
#. Empty list
|
||||||
|
|
||||||
|
``DISABLE_UNINSTALLED <bool>``
|
||||||
|
Overrides the search behavior for "uninstalled" package files. These are
|
||||||
|
package files with an "-uninstalled" suffix which describe packages integrated
|
||||||
|
directly from a build tree.
|
||||||
|
|
||||||
|
Normally such package files have higher priority than "installed" packages.
|
||||||
|
When ``DISABLE_UNINSTALLED`` is true, searching for "uninstalled" packages
|
||||||
|
is disabled.
|
||||||
|
|
||||||
|
When this option is not provided, the default search behavior is determined
|
||||||
|
by the first available of the following values:
|
||||||
|
|
||||||
|
#. ``CMAKE_PKG_CONFIG_DISABLE_UNINSTALLED``
|
||||||
|
#. If the ``PKG_CONFIG_DISABLE_UNINSTALLED`` environment variable is defined
|
||||||
|
the search is disabled, otherwise it is enabled.
|
||||||
|
|
||||||
|
``PC_SYSROOT_DIR <path>``
|
||||||
|
Overrides the root path which will be prepended to paths specified by ``-I``
|
||||||
|
compile flags and ``-L`` library search locations; also used to derive the
|
||||||
|
``pc_sysrootdir`` package variable.
|
||||||
|
|
||||||
|
When this option is not provided, the default root path is provided by the
|
||||||
|
first available of the following values:
|
||||||
|
|
||||||
|
#. ``CMAKE_PKG_CONFIG_SYSROOT_DIR``
|
||||||
|
#. The ``PKG_CONFIG_SYSROOT_DIR`` environment variable
|
||||||
|
#. If no root path is available, nothing will be prepended to include or
|
||||||
|
library directory paths and ``pc_sysrootdir`` will be set to ``/``
|
||||||
|
|
||||||
|
``TOP_BUILD_DIR <path>``
|
||||||
|
Overrides the top build directory path used to derived the ``pc_top_builddir``
|
||||||
|
package variable.
|
||||||
|
|
||||||
|
When this option is not provided, the default top build directory path is
|
||||||
|
the first available of the following values:
|
||||||
|
|
||||||
|
#. ``CMAKE_PKG_CONFIG_TOP_BUILD_DIR``
|
||||||
|
#. The ``PKG_CONFIG_TOP_BUILD_DIR`` environment variable
|
||||||
|
#. If no top build directory path is available, the ``pc_top_builddir``
|
||||||
|
package variable is not set
|
||||||
|

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, continuous, 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``.

Running Tests in the Build Tree
|
||||||
|
===============================
|
||||||
|
|
||||||
|
After `Building CMake`_, one may run the test suite in the build tree
|
||||||
|
using `ctest(1)`_:
|
||||||
|
|
||||||
|
* With a single-configuration CMake generator, such as ``Ninja``
|
||||||
|
or ``Unix Makefiles``, one may simply run ``ctest``:
|
||||||
|
|
||||||
|
.. code-block:: console
|
||||||
|
|
||||||
|
$ ctest
|
||||||
|
|
||||||
|
* With a multi-configuration CMake generator, such as
|
||||||
|
``Ninja Multi-Config``, ``Visual Studio``, or ``Xcode``,
|
||||||
|
one must tell ``ctest`` which configuration to test
|
||||||
|
by passing the ``-C <config>`` option:
|
||||||
|
|
||||||
|
.. code-block:: console
|
||||||
|
|
||||||
|
$ ctest -C Debug
|
||||||
|
|
||||||
|
Some useful `ctest(1)`_ options include:
|
||||||
|
|
||||||
|
``-N``
|
||||||
|
List test names without running them.
|
||||||
|
|
||||||
|
``-V``
|
||||||
|
Show verbose output from each test.
|
||||||
|
|
||||||
|
``-j <N>``
|
||||||
|
Run to run up to ``N`` tests concurrently.
|
||||||
|
|
||||||
CMake Dashboard Scripts
|
``-R <regex>``
|
||||||
=======================
|
Select tests for which the regular expression matches a substring
|
||||||
|
of their name.
|
||||||
|
|
||||||
The *integration testing* step of the `CMake Review Process`_ uses a set of
|
Cleaning Test Build Trees
|
||||||
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
|
Many CMake tests create their own test project build trees underneath
|
||||||
nightly, continuous, and experimental testing of CMake. Use the following
|
the ``Tests/`` directory at the top of the CMake build tree. These
|
||||||
commands to set up a new integration testing client:
|
build trees are left behind after testing completes in order to
|
||||||
|
facilitate manual investigation of results. Many of the tests do *not*
|
||||||
|
clean their build trees if they are run again, with the exception of
|
||||||
|
tests using the `RunCMake`_ infrastructure.
|
||||||
|
|
||||||
|
In order to clear test build trees, drive the ``test_clean`` custom target
|
||||||
|
in the CMake build tree:
|
||||||
|
|
||||||
|
.. code-block:: console
|
||||||
|
|
||||||
|
$ cmake --build . --target test_clean
|
||||||
|
|
||||||
|
This removes the ``Tests/`` subdirectories created by individual tests
|
||||||
|
so they will use a fresh directory next time they run.

Running Tests with a Different Generator
|
||||||
|
========================================
|
||||||
|
|
||||||
|
After `Building CMake`_ with one CMake generator, one may configure the

one may configure a second build tree to drive tests with the
|
||||||
instructions to set up a testing client. As it instructs, create a

``Ninja Multi-Config`` generator:

Project Types
|
|
||||||
^^^^^^^^^^^^^
|
|
||||||
|
|
||||||
Only Visual C++ and C# projects may be generated (and Fortran with
|
|
||||||
Intel compiler integration). Other types of projects (JavaScript,
|
|
||||||
Powershell, Python, etc.) are not supported.

|
|
||||||
Platform Selection
|
|
||||||
^^^^^^^^^^^^^^^^^^
|
|
||||||
|
|
||||||
The default target platform name (architecture) is ``Win32``.
|
|
||||||
|
|
||||||
.. versionadded:: 3.1
|
|
||||||
The :variable:`CMAKE_GENERATOR_PLATFORM` variable may be set, perhaps
|
|
||||||
via the :option:`cmake -A` option, to specify a target platform
|
|
||||||
name (architecture). For example:
|
|
||||||
|
|
||||||
* ``cmake -G "Visual Studio 12 2013" -A Win32``
|
|
||||||
* ``cmake -G "Visual Studio 12 2013" -A x64``
|
|
||||||
* ``cmake -G "Visual Studio 12 2013" -A ARM``
|
|
||||||
|
|
||||||
For compatibility with CMake versions prior to 3.1, one may specify
|
|
||||||
a target platform name optionally at the end of the generator name.
|
|
||||||
This is supported only for:
|
|
||||||
|
|
||||||
``Visual Studio 12 2013 Win64``
|
|
||||||
Specify target platform ``x64``.

The :module:`CPack` module enables per-machine installation by default
|
||||||
|
in the :cpack_gen:`CPack WIX Generator`.
|
||||||
|
|
||||||
|
The :cpack_gen:`CPack WIX Generator`'s :variable:`CPACK_WIX_INSTALL_SCOPE`
|
||||||
|
option controls the scope of the generated Windows Installer package.
|
||||||
|
When :variable:`CPACK_WIX_VERSION` is set to 4 or higher, the default scope
|
||||||
|
is ``perMachine``. However, when using WIX 3 the default scope is ``NONE``,
|
||||||
|
and CPack does not set any ``InstallScope`` in the package specification.
|
||||||
|
The resulting installer requires administrative privileges and installs
|
||||||
|
into the system-wide ``ProgramFiles`` directory, but the start menu entry
|
||||||
|
and uninstaller registration are created only for the current user.
|
||||||
|
|
||||||
|
The :module:`CPack` module in CMake 3.30 and older does not specify any
|
||||||
|
:variable:`CPACK_WIX_INSTALL_SCOPE` value by default, so CPack uses no
|
||||||
|
installation scope by default with WIX 3. CMake 3.31 and newer instead
|
||||||
|
prefer to set :variable:`CPACK_WIX_INSTALL_SCOPE` to ``perMachine`` by
|
||||||
|
default to make the behavior consistent across all WIX versions. This
|

|
policy provides compatibility for projects that have not been updated
|

to expect ``perMachine`` behavior.

:command:`cmake_parse_arguments(PARSE_ARGV)` defines a variable for an empty
|
||||||
|
string after a single-value keyword.
|
||||||
|
|
||||||
|
One of the main reasons for using the ``PARSE_ARGV`` form of the
|
||||||
|
:command:`cmake_parse_arguments` command is to more robustly handle corner
|
||||||
|
cases related to empty values. The non-``PARSE_ARGV`` form doesn't preserve
|
||||||
|
empty arguments, but the ``PARSE_ARGV`` form does. For each single-value
|
||||||
|
keyword given, a variable should be defined if the keyword is present, even
|
||||||
|
if it is followed by an empty string.
|
||||||
|
|
||||||
|
Prior to CMake 3.31, no variable would be defined if the value given after a
|
||||||
|
single-value keyword was an empty string. This meant the code could not detect
|
||||||
|
the difference between the keyword not being given, and it being given but with
|
||||||
|
an empty value, except by iterating over all the arguments and checking if the
|
||||||
|
keyword is present.
|
||||||
|
|
||||||
|
For the ``OLD`` behavior of this policy,
|
||||||
|
:command:`cmake_parse_arguments(PARSE_ARGV)` does not define a variable for a
|
||||||
|
single-value keyword followed by an empty string, or followed by no value at
|
||||||
|
all.
|
||||||
|
|
||||||
|
For the ``NEW`` behavior, :command:`cmake_parse_arguments(PARSE_ARGV)` always
|
||||||
|
defines a variable for each keyword given in the arguments, even a single-value
|
||||||
|
keyword with an empty string as its value or no value at all. With the
|
||||||
|
``NEW`` behavior, the code can robustly check if a single-value keyword was
|
||||||
|
given using just ``if(DEFINED <prefix>_<keyword>)``.

CMake 3.30 and earlier silently ignored unsupported keywords and missing or

||||||
|
invalid arguments for the different forms of the :command:`add_custom_command`
|
||||||
|
command. CMake 3.31 implements more rigorous argument checking and will flag

invalid or missing arguments as errors.

|
The ``OLD`` behavior of this policy will accept the same invalid keywords or
|
||||||
|
arguments as CMake 3.30 and earlier. The ``NEW`` behavior will flag the
|
||||||
|
following as errors that previously went unreported:
|
||||||
|
|
||||||
|
* The ``OUTPUT`` form does not accept ``PRE_BUILD``, ``PRE_LINK``, or
|
||||||
|
``POST_BUILD`` keywords.
|
||||||
|
* When the ``APPEND`` keyword is given, the ``OUTPUT`` form also does not
|
||||||
|
accept ``BYPRODUCTS``, ``COMMAND_EXPAND_LISTS``, ``DEPENDS_EXPLICIT_ONLY``,
|
||||||
|
``DEPFILE``, ``JOB_POOL``, ``JOB_SERVER_AWARE``, ``USES_TERMINAL``, or
|
||||||
|
``VERBATIM`` keywords.
|
||||||
|
* The ``TARGET`` form requires exactly one of ``PRE_BUILD``, ``PRE_LINK``, or
|
||||||
|
``POST_BUILD`` to be given. Previously, if none were given, ``POST_BUILD``
|
||||||
|
was assumed, or if multiple keywords were given, the last one was used.
|
||||||
|
* The ``TARGET`` form does not accept ``DEPENDS``, ``DEPENDS_EXPLICIT_ONLY``,
|
||||||
|
``DEPFILE``, ``IMPLICIT_DEPENDS``, ``MAIN_DEPENDENCY``, ``JOB_POOL``,
|
||||||
|
``JOB_SERVER_AWARE``, or ``USES_TERMINAL`` keywords.
|
||||||
|
* The ``TARGET`` form now requires at least one ``COMMAND`` to be given.
|
||||||
|
* If a keyword expects a value to be given after it, but no value is provided,
|
||||||
|
that was previously treated as though the keyword was not given at all.
|
||||||
|
* The ``COMMENT`` keyword expects exactly one value after it. If multiple
|
||||||
|
values are given, or if the ``COMMENT`` keyword is given more than once,
|
||||||
|
this is an error.

:command:`execute_process` ``ENCODING`` is ``UTF-8`` by default.

|
|

The ``ENCODING`` option is meaningful only on Windows. It specifies the
|

character encoding expected in the process's output on stdout and stderr.
|
||||||
|
In CMake 3.14 and below the default encoding was ``NONE``, which corresponds

to CMake's internal UTF-8 encoding. In CMake 3.15 through CMake 3.30 the
|
||||||
|
default encoding was accidentally changed to ``AUTO``, but the change went
|
||||||
|
unnoticed and was not documented.
|
||||||
|
|

CMake 3.31 and above prefer the ``ENCODING`` default to be ``UTF-8``.
|

|
This policy provides compatibility with projects that may have been

|

The :command:`install` command has a number of different forms, and most of

them take a ``DESTINATION`` keyword, some in more than one place.
|

|
CMake 3.30 and earlier used the value given after the ``DESTINATION`` keyword

assumes the path contains no ``..`` or ``.`` path components when computing

CMake 3.31 normalizes all ``DESTINATION`` values given in any form of the
|
||||||
|
:command:`install` command, except for the ``INCLUDES DESTINATION`` of the
|
||||||
|
:command:`install(TARGETS)` form. The normalization performed is the same
|
||||||
|
as for the :command:`cmake_path` command (see :ref:`Normalization`).
|
||||||
|
|
||||||
|
The ``OLD`` behavior of this policy performs no translation on the
|
||||||
|
``DESTINATION`` values of any :command:`install` command. They are used
|
||||||
|
exactly as provided. If a destination path contains ``..`` or ``.`` path
|
||||||
|
components, :command:`install(EXPORT)` will use the same wrong paths as
|
||||||
|
CMake 3.30 and earlier.
|
||||||
|
|
||||||
|
The ``NEW`` behavior will normalize all ``DESTINATION`` values except for
|
||||||
|
``INCLUDES DESTINATION``. If a destination path contains a generator
|
||||||
|
expression, it will be wrapped in a ``$<PATH:CMAKE_PATH,NORMALIZE,...>``
|
||||||
|
generator expression.
|
||||||
|
|
||||||
|
This policy was introduced in CMake version 3.31.
|
||||||
|
It may be set by :command:`cmake_policy` or :command:`cmake_minimum_required`.
|
||||||
|
If it is not set, CMake will warn if it detects a path that would be different
|
||||||
|
if normalized, and uses ``OLD`` behavior. If a destination path contains a
|
||||||
|
generator expression, no such warning will be issued regardless of the value.

of the static libraries rather than the fist occurrence when they are

:variable:`<PROJECT-NAME>_SOURCE_DIR`, :variable:`<PROJECT-NAME>_BINARY_DIR`,
|
||||||
|
and :variable:`<PROJECT-NAME>_IS_TOP_LEVEL` as cache entries, but not as

normal variables. CMake 3.30 started setting them as normal variables,

On AIX, enable creation of a shared library archive. This places
|
||||||
|
the shared object ``.so`` file inside an archive ``.a`` file.
|
||||||
|
|
||||||
|
By default, CMake creates shared libraries on AIX as plain
|
||||||
|
shared object ``.so`` files for consistency with other UNIX platforms.
|
||||||
|
Alternatively, set this property to a true value to create a shared
|
||||||
|
library archive instead, as is AIX convention.
|
||||||
|
|
||||||
|
The shared object name in the archive encodes version information from
|
||||||
|
the :prop_tgt:`SOVERSION` target property, if set, and otherwise from
|
||||||
|
the :prop_tgt:`VERSION` target property, if set.
|
||||||
|
|
||||||
|
This property defaults to :variable:`CMAKE_AIX_SHARED_LIBRARY_ARCHIVE`
|

|
by :command:`add_library`.

LINK_LIBRARIES_STRATEGY
|
||||||
|
-----------------------
|
||||||
|
|
||||||
|
.. versionadded:: 3.31
|
||||||
|
|
||||||
|
Specify a strategy for ordering a target's direct link dependencies
|
||||||
|
on linker command lines. This property is initialized by the value of the
|
||||||
|
:variable:`CMAKE_LINK_LIBRARIES_STRATEGY` variable if it is set when a
|
||||||
|
target is created.
|
||||||
|
|
||||||
|
CMake generates a target's link line using its :ref:`Target Link Properties`.
|
||||||
|
In particular, the :prop_tgt:`LINK_LIBRARIES` target property records the
|
||||||
|
target's direct link dependencies, typically populated by calls to
|
||||||
|
:command:`target_link_libraries`. Indirect link dependencies are
|
||||||
|
propagated from those entries of :prop_tgt:`LINK_LIBRARIES` that name
|
||||||
|
library targets by following the transitive closure of their
|
||||||
|
:prop_tgt:`INTERFACE_LINK_LIBRARIES` properties. CMake supports multiple
|
||||||
|
strategies for nominally ordering direct and indirect link dependencies,
|
||||||
|
which are then filtered for `Toolchain-Specific Behavior`_.
|
||||||
|
|
||||||
|
Consider this example for the strategies below:
|
||||||
|
|
||||||
|
.. code-block:: cmake
|
||||||
|
|
||||||
|
add_library(A STATIC ...)
|
||||||
|
add_library(B STATIC ...)
|
||||||
|
add_library(C STATIC ...)
|
||||||
|
add_executable(main ...)
|
||||||
|
target_link_libraries(B PRIVATE A)
|
||||||
|
target_link_libraries(C PRIVATE A)
|
||||||
|
target_link_libraries(main PRIVATE A B C)
|
||||||
|
|
||||||
|
The supported strategies are:
|
||||||
|
|
||||||
|
``REORDER_MINIMALLY``
|
||||||
|
Entries of :prop_tgt:`LINK_LIBRARIES` always appear first and in their
|
||||||
|
original order. Indirect link dependencies not satisfied by the
|
||||||
|
original entries may be reordered and de-duplicated with respect to
|
||||||
|
one another, but are always appended after the original entries.
|
||||||
|
This may result in less efficient link lines, but gives projects
|
||||||
|
control of ordering among independent entries. Such control may be
|
||||||
|
important when intermixing link flags with libraries, or when multiple
|
||||||
|
libraries provide a given symbol.
|
||||||
|
|
||||||
|
This is the default.
|
||||||
|
|
||||||
|
In the above example, this strategy computes a link line for ``main``
|
||||||
|
by starting with its original entries ``A B C``, and then appends
|
||||||
|
another ``A`` to satisfy the dependencies of ``B`` and ``C`` on ``A``.
|
||||||
|
The nominal order produced by this strategy is ``A B C A``.
|
||||||
|
|
||||||
|
Note that additional filtering for `Toolchain-Specific Behavior`_
|
||||||
|
may de-duplicate ``A`` on the actual linker invocation in the
|
||||||
|
generated build system, resulting in either ``A B C`` or ``B C A``.
|
||||||
|
|
||||||
|
``REORDER_FREELY``
|
||||||
|
Entries of :prop_tgt:`LINK_LIBRARIES` may be reordered, de-duplicated,
|
||||||
|
and intermixed with indirect link dependencies. This may result in
|
||||||
|
more efficient link lines, but does not give projects any control of
|
||||||
|
ordering among independent entries.
|
||||||
|
|
||||||
|
In the above example, this strategy computes a link line for ``main``
|
||||||
|
by re-ordering its original entries ``A B C`` to satisfy the
|
||||||
|
dependencies of ``B`` and ``C`` on ``A``.
|
||||||
|
The nominal order produced by this strategy is ``B C A``.
|
||||||
|
|
||||||
|
Toolchain-Specific Behavior
|
||||||
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||||
|
|
||||||
|
After one of the above strategies produces a nominal order among
|
||||||
|
direct and indirect link dependencies, the actual linker invocation
|
||||||
|
in the generated build system may de-duplicate entries based on
|
||||||
|
platform-specific requirements and linker capabilities.
|
||||||
|
See policy :policy:`CMP0156`.
|
||||||
|
|
||||||
|
For example, if the ``REORDER_MINIMALLY`` strategy produces ``A B C A``,
|
||||||
|
the actual link line may de-duplicate ``A`` as follows:
|
||||||
|
|
||||||
|
* If ``A`` is a static library and the linker re-scans automatically,
|
||||||
|
the first occurrence is kept, resulting in ``A B C``.
|
||||||
|
See policy :policy:`CMP0179`
|
||||||
|
|
||||||
|
* If ``A`` is a shared library on Windows, the first
|
||||||
|
occurrence is kept, resulting in ``A B C``.
|
||||||
|
|
||||||
|
* If ``A`` is a shared library on macOS or UNIX platforms, the last
|
||||||
|
occurrence is kept, resulting in ``B C A``.

Changes made since CMake 3.30 include the following.
|
||||||
|
|
||||||
|
New Features
|
||||||
|
============
|
||||||
|
|
||||||
|
Presets
|
||||||
|
-------
|
||||||
|
|
||||||
|
* :manual:`cmake-presets(7)` files may now include comments using the key
|
||||||
|
``$comment`` at any level within the JSON object to provide documentation.
|
||||||
|
|
||||||
|
* :manual:`cmake-presets(7)` files may now request graphviz output using
|
||||||
|
the ``graphviz`` key in a configure preset.
|
||||||
|
|
||||||
|
Generators
|
||||||
|
----------
|
||||||
|
|
||||||
|
* The :ref:`Ninja Generators` and :ref:`Makefile Generators` now produce
|
||||||
|
a ``codegen`` build target. See policy :policy:`CMP0171`. It drives a
|
||||||
|
subset of the build graph sufficient to run custom commands created with
|
||||||
|
:command:`add_custom_command`'s new ``CODEGEN`` option.
|
||||||
|
|
||||||
|
Command-Line
|
||||||
|
------------
|
||||||
|
|
||||||
|
* The :option:`cmake --workflow` mode now accepts a preset name as the first
|
||||||
|
argument, allowing the simpler command line
|
||||||
|
:option:`cmake --workflow \<preset\> <cmake--workflow --preset>`.
|
||||||
|
|
||||||
|
* The :option:`cmake -LR[A][H]` option was added to list cache entries
|
||||||
|
whose names match a regular expression.
|
||||||
|
|
||||||
|
Compilers
|
||||||
|
---------
|
||||||
|
|
||||||
|
* The LFortran compiler is now supported with
|
||||||
|
:variable:`compiler id <CMAKE_<LANG>_COMPILER_ID>` ``LFortran``.
|
||||||
|
|
||||||
|
Commands
|
||||||
|
--------
|
||||||
|
|
||||||
|
* The :command:`add_custom_command` command gained a ``CODEGEN`` option
|
||||||
|
to mark a custom command's outputs as dependencies of a ``codegen`` target.
|
||||||
|
See policy :policy:`CMP0171`.
|
||||||
|
|
||||||
|
* The :command:`cmake_pkg_config` command was added as an endpoint for using
|
||||||
|
CMake's native pkg-config format parser. The only supported option in this
|
||||||
|
release is ``EXTRACT``, which provides low-level access to the values
|
||||||
|
produced by parsing a pkg-config file. For most users, this is not yet a
|
||||||
|
suitable replacement for the :module:`FindPkgConfig` module.
|
||||||
|
|
||||||
|
* The :command:`file(ARCHIVE_CREATE)` command gained a ``WORKING_DIRECTORY``
|
||||||
|
option to specify a working directory for the archiving process.
|
||||||
|
|
||||||
|
* The :command:`file(MAKE_DIRECTORY)` command gained a ``RESULT`` option
|
||||||
|
to capture failure in a result variable.
|
||||||
|
|
||||||
|
* The :command:`install(FILES)` and :command:`install(DIRECTORY)` commands'
|
||||||
|
``TYPE`` argument gained support for a ``LIBEXEC`` type.
|
||||||
|
|
||||||
|
Variables
|
||||||
|
---------
|
||||||
|
|
||||||
|
* The :variable:`CMAKE_AIX_SHARED_LIBRARY_ARCHIVE` variable and corresponding
|
||||||
|
:prop_tgt:`AIX_SHARED_LIBRARY_ARCHIVE` target property were added to
|
||||||
|
create shared libraries on AIX as shared library archives.
|
||||||
|
|
||||||
|
* The :variable:`CMAKE_EXPORT_BUILD_DATABASE` variable, a corresponding
|
||||||
|
:envvar:`CMAKE_EXPORT_BUILD_DATABASE` environment variable, and an
|
||||||
|
:prop_tgt:`EXPORT_BUILD_DATABASE` target property, were added to
|
||||||
|
enable exporting C++ module compile commands.
|
||||||
|
This is only supported with :ref:`Ninja Generators`.
|
||||||
|
|
||||||
|
* The :variable:`CMAKE_HOST_EXECUTABLE_SUFFIX` variable was added to
|
||||||
|
provide the suffix for executable names on the host platform.
|
||||||
|
|
||||||
|
* The :variable:`CMAKE_<LANG>_HOST_COMPILER_ID` and
|
||||||
|
:variable:`CMAKE_<LANG>_HOST_COMPILER_VERSION` variables were added,
|
||||||
|
where ``<LANG>`` is either ``CUDA`` or ``HIP``. They are populated
|
||||||
|
when :variable:`CMAKE_<LANG>_COMPILER_ID` is ``NVIDIA`` to identify
|
||||||
|
NVCC's host compiler.
|
||||||
|
|
||||||
|
* The :variable:`CMAKE_<LANG>_STANDARD_LINK_DIRECTORIES` variable was added.
|
||||||
|
Toolchain files can set this variable to control which link library directory
|
||||||
|
paths are always passed to the compiler for the specified language.
|
||||||
|
|
||||||
|
* The :variable:`CMAKE_LINK_LIBRARIES_STRATEGY` variable and
|
||||||
|
corresponding :prop_tgt:`LINK_LIBRARIES_STRATEGY` target
|
||||||
|
property were added to optionally specify the strategy
|
||||||
|
CMake uses to generate link lines.
|
||||||
|
|
||||||
|
Properties
|
||||||
|
----------
|
||||||
|
|
||||||
|
* The :prop_tgt:`MACOSX_FRAMEWORK_BUNDLE_NAME <MACOSX_FRAMEWORK_INFO_PLIST>`
|
||||||
|
target property was added to set the ``CFBundleName`` key in an Apple
|
||||||
|
:prop_tgt:`FRAMEWORK`'s ``Info.plist`` file.
|
||||||
|
|
||||||
|
* The :prop_tgt:`UNITY_BUILD` target property now supports the
|
||||||
|
``CUDA`` language.
|
||||||
|
|
||||||
|
* The :prop_tgt:`VS_FRAMEWORK_REFERENCES` target property was added
|
||||||
|
to tell :ref:`Visual Studio Generators` to add framework references.
|
||||||
|
|
||||||
|
Modules
|
||||||
|
-------
|
||||||
|
|
||||||
|
* Check modules now support a ``CMAKE_REQUIRED_LINK_DIRECTORIES`` variable.
|
||||||
|
The following modules gained this support:
|
||||||
|
|
||||||
|
* :module:`CMakePushCheckState`
|
||||||
|
* :module:`CheckCCompilerFlag`
|
||||||
|
* :module:`CheckCSourceCompiles`
|
||||||
|
* :module:`CheckCSourceRuns`
|

Deprecated and Removed Features
|
||||||
|
===============================
|
||||||
|
|
||||||
|
* Compatibility with versions of CMake older than 3.10 is now deprecated
|
||||||
|
and will be removed from a future version. Calls to
|
||||||
|
:command:`cmake_minimum_required` or :command:`cmake_policy` that set
|
||||||
|
the policy version to an older value now issue a deprecation diagnostic.
|
||||||
|
|
||||||
|
* The :module:`CMakeFindFrameworks` module has been deprecated via
|
||||||
|
:policy:`CMP0173`. Projects should use :command:`find_library` instead.
|
||||||
|
|
||||||
|
* The :generator:`Visual Studio 12 2013` generator has been removed.
|
||||||
|
|
||||||
|
Other Changes
|
||||||
|
=============
|
||||||
|
|
||||||
|
* When static libraries on link lines are de-duplicated (by policy
|
||||||
|
:policy:`CMP0156`), the first occurrence is now kept on all platforms.
|
||||||
|
See policy :policy:`CMP0179`.
|
||||||
|
|
||||||
|
* Empty list elements in the :prop_tgt:`TEST_LAUNCHER` and
|
||||||
|
:prop_tgt:`CROSSCOMPILING_EMULATOR` target properties are now preserved by:
|
||||||
|
|
||||||
|
* The :command:`add_test` command.
|
||||||
|
* The :command:`ExternalData_Add_Test` command from the
|
||||||
|
:module:`ExternalData` module.
|
||||||
|
* The :command:`gtest_add_tests` and :command:`gtest_discover_tests`
|
||||||
|
commands from the :module:`GoogleTest` module.
|
||||||
|
Empty list elements after the ``EXTRA_ARGS`` keyword of these
|
||||||
|
two commands are also now preserved.
|
||||||
|
|
||||||
|
See policy :policy:`CMP0178`.
|
||||||
|
|
||||||
|
* The :command:`execute_process` command's ``ENCODING`` option,
|
||||||
|
meaningful on Windows, now defaults to ``UTF-8``.
|
||||||
|
See policy :policy:`CMP0176`.
|
||||||
|
|
||||||
|
* The :command:`file(DOWNLOAD)` and :command:`file(UPLOAD)` commands now
|
||||||
|
verify TLS server certificates for connections to ``https://`` URLs by
|
||||||
|
default. See the :variable:`CMAKE_TLS_VERIFY` variable for details.
|
||||||
|
This change was made without a policy so that users are protected
|
||||||
|
even when building projects that have not been updated.
|
||||||
|
Users may set the :envvar:`CMAKE_TLS_VERIFY` environment
|
||||||
|
variable to ``0`` to restore the old default.
|
||||||
|
|
||||||
|
* The :command:`file(DOWNLOAD)` and :command:`file(UPLOAD)` commands now
|
||||||
|
require TLS 1.2 or higher for connections to ``https://`` URLs by default.
|
||||||
|
See the :variable:`CMAKE_TLS_VERSION` variable for details.
|
||||||
|
|
||||||
|
* The :command:`file(GET_RUNTIME_DEPENDENCIES)` command was updated
|
||||||
|
to more closely match the dynamic loader's behavior on Linux.
|
||||||
|
|
||||||
|
* The :command:`install` command's ``DESTINATION`` arguments are
|
||||||
|
now :ref:`normalized <Normalization>`, with the exception
|
||||||
|
of ``INCLUDES DESTINATION`` arguments in :command:`install(TARGETS)`.
|
||||||
|
See policy :policy:`CMP0177`.
|
||||||
|
|
||||||
|
* The :command:`project` command now always sets
|
||||||
|
:variable:`<PROJECT-NAME>_SOURCE_DIR`, :variable:`<PROJECT-NAME>_BINARY_DIR`,
|
||||||
|
and :variable:`<PROJECT-NAME>_IS_TOP_LEVEL` as both normal variables and
|
||||||
|
cache entries. See policy :policy:`CMP0180`.
|
||||||
|
|
||||||
|
* The :command:`cmake_parse_arguments(PARSE_ARGV)` command now defines a
|
||||||
|
variable for an empty string after a single-value keyword. See policy
|
||||||
|
:policy:`CMP0174`.
