Changes made since CMake 3.4 include the following.
|
|
|
|
New Features
|
|
============
|
|
|
|
GUI
|
|
---
|
|
|
|
* The :manual:`cmake-gui(1)` gained options to control warnings about
|
|
deprecated functionality.
|
|
|
|
* The :manual:`cmake-gui(1)` learned an option to set the toolset
|
|
to be used with VS IDE and Xcode generators, much like the
|
|
existing ``-T`` option to :manual:`cmake(1)`.
|
|
|
|
* The :manual:`cmake-gui(1)` gained a Regular Expression Explorer which
|
|
may be used to create and evaluate regular expressions in real-time.
|
|
The explorer window is available via the ``Tools`` menu.
|
|
|
|
Command-Line
|
|
------------
|
|
|
|
* The ``-Wdev`` and ``-Wno-dev`` :manual:`cmake(1)` options now also enable
|
|
and suppress the deprecated warnings output by default.
|
|
|
|
* The suppression of developer warnings as errors can now be controlled with
|
|
the new ``-Werror=dev`` and ``-Wno-error=dev`` :manual:`cmake(1)` options.
|
|
|
|
* The :manual:`cmake(1)` ``-E`` command-line tools ``copy``,
|
|
``copy_if_different``, ``copy_directory``, and ``make_directory``
|
|
learned to support multiple input files or directories.
|
|
|
|
Commands
|
|
--------
|
|
|
|
* The :command:`cmake_parse_arguments` command is now implemented natively.
|
|
The :module:`CMakeParseArguments` module remains as an empty placeholder
|
|
for compatibility.
|
|
|
|
* The :command:`install(DIRECTORY)` command learned to support
|
|
:manual:`generator expressions <cmake-generator-expressions(7)>`
|
|
in the list of directories.
|
|
|
|
Variables
|
|
---------
|
|
|
|
* The :variable:`CMAKE_ERROR_DEPRECATED` variable can now be set using the
|
|
``-Werror=deprecated`` and ``-Wno-error=deprecated`` :manual:`cmake(1)`
|
|
options.
|
|
|
|
* The :variable:`CMAKE_WARN_DEPRECATED` variable can now be set using the
|
|
``-Wdeprecated`` and ``-Wno-deprecated`` :manual:`cmake(1)` options.
|
|
|
|
Properties
|
|
----------
|
|
|
|
* The :prop_tgt:`VS_GLOBAL_<variable>` target property is now implemented
|
|
for VS 2010 and above. Previously it worked only in VS 2008 and below.
|
|
|
|
Modules
|
|
-------
|
|
|
|
* The :module:`ExternalProject` module learned a new ``GIT_REMOTE_NAME``
|
|
option to control the ``git clone --origin`` value.
|
|
|
|
* The :module:`FindBoost` module now provides imported targets
|
|
such as ``Boost::boost`` and ``Boost::filesystem``.
|
|
|
|
* The :module:`FindFLEX` module ``FLEX_TARGET`` macro learned a
|
|
new ``DEFINES_FILE`` option to specify a custom output header
|
|
to be generated.
|
|
|
|
* The :module:`FindGTest` module now provides imported targets.
|
|
|
|
* The :module:`FindGTK2` module, when ``GTK2_USE_IMPORTED_TARGETS`` is
|
|
enabled, now sets ``GTK2_LIBRARIES`` to contain the list of imported
|
|
targets instead of the paths to the libraries. Moreover it now sets
|
|
a new ``GTK2_TARGETS`` variable containing all the targets imported.
|
|
|
|
* The :module:`FindOpenMP` module learned to support Clang.
|
|
|
|
* The :module:`FindOpenSSL` module gained a new
|
|
``OPENSSL_MSVC_STATIC_RT`` option to search for libraries using
|
|
the MSVC static runtime.
|
|
|
|
* The :module:`FindPNG` module now provides imported targets.
|
|
|
|
* The :module:`FindTIFF` module now provides imported targets.
|
|
|
|
* A :module:`FindXalanC` module was introduced to find the
|
|
Apache Xalan-C++ XSL transform processing library.
|
|
|
|
* The :module:`FindXercesC` module now provides imported targets.
|
|
|
|
Platforms
|
|
---------
|
|
|
|
* Support was added for the ARM Compiler (arm.com) with compiler id ``ARMCC``.
|
|
|
|
* A new platform file for cross-compiling in the Cray Linux Environment to
|
|
target compute nodes was added. See
|
|
:ref:`Cross Compiling for the Cray Linux Environment <Cray Cross-Compile>`
|
|
for usage details.
|
|
|
|
* The :manual:`Compile Features <cmake-compile-features(7)>` functionality
|
|
is now aware of features supported by Clang compilers on Windows (MinGW).
|
|
|
|
* When building for embedded Apple platforms like iOS CMake learned to build and
|
|
install combined targets which contain both a device and a simulator build.
|
|
This behavior can be enabled by setting the :prop_tgt:`IOS_INSTALL_COMBINED`
|
|
target property.
|
|
|
|
CPack
|
|
-----
|
|
|
|
* The :cpack_gen:`CPack DragNDrop Generator` learned new variable to
|
|
specify AppleScript file run to customize appearance of ``DragNDrop``
|
|
installer folder, including background image setting using supplied
|
|
PNG or multi-resolution TIFF file.
|
|
See the :variable:`CPACK_DMG_DS_STORE_SETUP_SCRIPT` and
|
|
:variable:`CPACK_DMG_BACKGROUND_IMAGE` variables.
|
|
|
|
* The :cpack_gen:`CPack DEB Generator` learned to set the optional config
|
|
file ``Source`` field using a monolithic or per-component variable.
|
|
See :variable:`CPACK_DEBIAN_PACKAGE_SOURCE`.
|
|
|
|
* The :cpack_gen:`CPack DEB Generator` learned to set Package, Section
|
|
and Priority control fields per-component.
|
|
See variables :variable:`CPACK_DEBIAN_<COMPONENT>_PACKAGE_SECTION` and
|
|
:variable:`CPACK_DEBIAN_<COMPONENT>_PACKAGE_PRIORITY`.
|
|
|
|
* The :cpack_gen:`CPack DragNDrop Generator` learned to add
|
|
multi-lingual SLAs to a DMG which is presented to the user when they try to
|
|
mount the DMG. See the :variable:`CPACK_DMG_SLA_LANGUAGES` and
|
|
:variable:`CPACK_DMG_SLA_DIR` variables for details.
|
|
|
|
* The :cpack_gen:`CPack NSIS Generator` learned new variables to
|
|
add bitmaps to the installer.
|
|
See the :variable:`CPACK_NSIS_MUI_WELCOMEFINISHPAGE_BITMAP`
|
|
and :variable:`CPACK_NSIS_MUI_UNWELCOMEFINISHPAGE_BITMAP` variables.
|
|
|
|
* The :cpack_gen:`CPack RPM Generator` learned to set Name and Group
|
|
control fields per-component.
|
|
See :variable:`CPACK_RPM_<component>_PACKAGE_NAME`
|
|
and :variable:`CPACK_RPM_<component>_PACKAGE_GROUP`.
|
|
|
|
Other
|
|
-----
|
|
|
|
* Warnings about deprecated functionality are now enabled by default.
|
|
They may be suppressed with ``-Wno-deprecated`` or by setting the
|
|
:variable:`CMAKE_WARN_DEPRECATED` variable to false.
|
|
|
|
Deprecated and Removed Features
|
|
===============================
|
|
|
|
* The :manual:`cmake(1)` ``-E time`` command now properly passes arguments
|
|
with spaces or special characters through to the child process. This
|
|
may break scripts that worked around the bug with their own extra
|
|
quoting or escaping.
|
|
|
|
* The :generator:`Xcode` generator was fixed to escape backslashes in
|
|
strings consistently with other generators. Projects that previously
|
|
worked around the inconsistecy with an extra level of backslashes
|
|
conditioned on the Xcode generator must be updated to remove the
|
|
workaround for CMake 3.5 and greater.
|
|
|
|
Other Changes
|
|
=============
|
|
|
|
* The :generator:`Visual Studio 14 2015` generator learned to map the
|
|
``/debug:fastlink`` linker flag to the ``.vcxproj`` file property.
|
|
|
|
* The :module:`FindGTK2` module now configures the ``GTK2::sigc++`` imported
|
|
target to enable c++11 on its dependents when using sigc++ 2.5.1 or higher.
|
|
|
|
* The precompiled Windows binary provided on ``cmake.org`` is now a
|
|
``.msi`` package instead of an installer executable. One may need
|
|
to manually uninstall CMake versions lower than 3.5 before installing
|
|
the new package.
