+Changes made since CMake 3.12 include the following.
|
|
|
+
|
|
|
+New Features
|
|
|
+============
|
|
|
+
|
|
|
+Generators
|
|
|
+----------
|
|
|
+
|
|
|
+* The :ref:`Visual Studio Generators` for VS 2010 and above learned to
|
|
|
+ support the :prop_tgt:`INTERPROCEDURAL_OPTIMIZATION` target property
|
|
|
+ and supporting :module:`CheckIPOSupported` module.
|
|
|
+
|
|
|
+* The :generator:`Xcode` generator learned to configure more Xcode Scheme
|
|
|
+ fields. See the :variable:`CMAKE_XCODE_GENERATE_SCHEME` variable.
|
|
|
+
|
|
|
+* The :generator:`Green Hills MULTI` generator has been udpated:
|
|
|
+
|
|
|
+ - Added support for architecture selection through
|
|
|
+ :variable:`CMAKE_GENERATOR_PLATFORM`:
|
|
|
+ e.g. ``arm``, ``ppc``, and ``86``.
|
|
|
+
|
|
|
+ - Added support for toolset selection through
|
|
|
+ :variable:`CMAKE_GENERATOR_TOOLSET`,
|
|
|
+ e.g. ``comp_201205``, ``comp_201510``, ``comp_201722_beta``.
|
|
|
+
|
|
|
+ - Added support for platform selection through ``GHS_TARGET_PLATFORM``,
|
|
|
+ e.g. ``integrity``, ``linux``, ``standalone``, etc.
|
|
|
+
|
|
|
+ - No longer checks that ``arm`` based compilers are installed but ensures
|
|
|
+ that the correct ``gbuild.exe`` exists.
|
|
|
+
|
|
|
+ - No longer hard-codes ARM files, BSP, toolset, or OS locations.
|
|
|
+
|
|
|
+Command-Line
|
|
|
+------------
|
|
|
+
|
|
|
+* The :manual:`cmake(1)` command gained the ``-S <source_dir>``
|
|
|
+ command line option to specify the location of the source directory.
|
|
|
+ This option can be used independently of ``-B``.
|
|
|
+
|
|
|
+* The :manual:`cmake(1)` command gained the ``-B <build_dir>``
|
|
|
+ command line option to specify the location of the build directory.
|
|
|

|
|
|
+ options in the current directory.
|
|

|
|
|

|
+ See policy :policy:`CMP0079`.
|
|
|
+
|
|
|
+Variables
|
|
|
+---------
|
|
|
+
|
|
|
+* A :variable:`CMAKE_AUTOGEN_VERBOSE` variable was added to optionally
|
|
|
+ increase the verbosity of :prop_tgt:`AUTOMOC`, :prop_tgt:`AUTOUIC`
|
|
|
+ and :prop_tgt:`AUTORCC` from within CMake project code.
|
|
|
+
|
|
|

|
+ they are created.
|
|
|
+
|
|
|
+Properties
|
|
|
+----------
|
|
|
+
|
|
|
+* The :prop_tgt:`DEPLOYMENT_ADDITIONAL_FILES` target property was
|
|
|
+ added to tell the :generator:`Visual Studio 9 2008` generator
|
|
|
+ to specify additional files for deployment to WinCE devices
|
|
|
+ for remote debugging.

|
+* :prop_tgt:`LINK_DIRECTORIES` and :prop_tgt:`INTERFACE_LINK_DIRECTORIES`
|
|
|
+ target properties were added to collect link directories for a target
|
|
|
+ and its dependents. Use the :command:`target_link_directories` command
|
|
|
+ to set them.
|
|
|
+
|
|
|
+* :prop_tgt:`LINK_OPTIONS` and :prop_tgt:`INTERFACE_LINK_OPTIONS` target
|
|
|
+ properties were added to collect link options for a target and its

|
|
+ dependents. Use the :command:`target_link_options` command to set them.
|
|
|
+

+* A :prop_dir:`LINK_OPTIONS` directory property was added to collect
|
|
|
+ link options for targets created under the current directory.
|
|
|
+ Use the :command:`add_link_options` command to set it.

+ to specify archiver options to use when creating static libraries.
|
|
|
+
|
|
|
+* A :prop_tgt:`VS_DEBUGGER_COMMAND_ARGUMENTS` target property was created to
|
|
|
+ set the debugging command line arguments with
|
|
|
+ :ref:`Visual Studio Generators` for VS 2010 and above.
|
|
|
+
|
|
|
+* A :prop_tgt:`VS_DEBUGGER_ENVIRONMENT` target property was created to
|
|

|
|
+ :ref:`Visual Studio Generators` for VS 2010 and above.
|
|
|
+
|
|
|
+* The :prop_tgt:`VS_DEBUGGER_COMMAND` and
|
|
|
+ :prop_tgt:`VS_DEBUGGER_WORKING_DIRECTORY` target properties
|
|
|
+ now support generator expressions.
|
|
|
+
|
|
|
+Modules
|
|
|
+-------
|
|
|
+
|
|
|
+* The :module:`FindCURL` module learned to find debug and release variants
|
|
|
+ separately.
|
|
|
+
|
|
|
+* The :module:`FindMatlab` module gained new components ``ENGINE_LIBRARY`` and
|
|
|
+ ``DATAARRAY_LIBRARY`` to request finding the Matlab C++ Engine and DataArray
|
|
|
+ libraries respectively.
|
|
|
+
|
|
|
+* The :module:`FindMatlab` module now explicitly exports mexFunction in Visual
|
|
|
+ Studio.
|
|
|
+
|
|
|
+* The :module:`FindMatlab` module gained a new ``MCC_COMPILER``
|
|
|
+ component to request finding the Matlab Compiler add-on.
|
|
|
+
|
|
|
+* The :module:`FindPkgConfig` module gained an option to create imported
|
|
|
+ targets in global scope.
|
|
|
+
|
|
|
+* Modules :module:`FindPython3`, :module:`FindPython2` and :module:`FindPython`
|
|
|
+ gain capability to control order of resource lookup on macOS (Framework) and
|
|
|
+ Windows (Registry).
|
|
|
+
|
|
|
+* The :module:`FindSubversion` module ``Subversion_WC_INFO`` command
|
|
|
+ gained an ``IGNORE_SVN_FAILURE`` option to suppress failures,
|
|
|
+ e.g. when the source tree is not under Subversion control.
|
|
|
+
|
|
|
+* The :module:`UseSWIG` module learned to manage target property
|
|
|
+ :prop_tgt:`INCLUDE_DIRECTORIES` for ``SWIG`` compilation.
|
|
|
+
|
|
|
+CTest
|
|
|
+-----
|
|
|
+
|
|
|
+* :manual:`ctest(1)` gained a ``--progress`` option to enable a live
|
|
|
+ test progress summary when output goes to a terminal.
|
|
|
+
|
|
|
+CPack
|
|
|
+-----
|
|
|
+
|
|
|
+* The :cpack_gen:`CPack Deb Generator` learned to split debug symbols into
|
|
|
+ a corresponding .ddeb package when ``CPACK_DEBIAN_DEBUGINFO_PACKAGE`` is
|
|
|
+ set.
|
|
|
+
|
|
|
+* The :cpack_gen:`CPack Deb Generator` learned to honor the ``SOURCE_DATE_EPOCH``
|
|
|
+ environment variable when packaging files. This is useful for generating
|
|
|
+ reproducible packages.
|
|
|
+
|
|
|
+* CPack gained a new :cpack_gen:`CPack External Generator` which is used to
|
|
|
+ export the CPack metadata in a format that other software can understand. The
|
|
|
+ intention of this generator is to allow external packaging software to take
|
|
|
+ advantage of CPack's features when it may not be possible to use CPack for
|
|
|
+ the entire packaging process.
|
|
|
+
|
|
|
+Deprecated and Removed Features
|
|
|
+===============================
|
|
|
+
|
|
|
+* An explicit deprecation diagnostic was added for policies ``CMP0055``
|
|
|
+ through ``CMP0063`` (``CMP0054`` and below were already deprecated).
|
|
|
+ The :manual:`cmake-policies(7)` manual explains that the OLD behaviors
|
|
|
+ of all policies are deprecated and that projects should port to the
|
|
|
+ NEW behaviors.
|
|
|
+
|
|
|
+Other Changes
|
|
|
+=============
|
|
|
+
|
|
|
+* The :command:`option` command now honors existing normal variables instead
|
|
|
+ of replacing them with a cache entry. See policy :policy:`CMP0077`.
|
|
|
+
|
|
|
+* The :ref:`Makefile Generators` learned to remove custom command and
|
|
|
+ custom target byproducts during ``make clean``.
|
|
|
+
|
|
|
+* The :command:`target_sources` command now interprets relative source file
|
|
|
+ paths as relative to the current source directory. This simplifies
|
|
|
+ incrementally building up a target's sources from subdirectories. The
|
|
|
+ :policy:`CMP0076` policy was added to provide backward compatibility with
|
|
|
+ the old behavior where required.
|
|
|
+
|
|
|
+* The :module:`BundleUtilities` module may no longer be included at configure
|
|
|
+ time. This was always a bug anyway. See policy :policy:`CMP0080`.
|
|
|
+
|
|
|
+* The :module:`UseSWIG` module has changed strategy for target naming.
|
|
|
+ See policy :policy:`CMP0078`.
|
|
|
+
|
|
|
+* The :prop_tgt:`LINK_DIRECTORIES` target property now expects absolute paths.
|
|
|
+ See policy :policy:`CMP0081`.
|
|
|
+
|
|
|
+* The CPack generators have been moved into their own separate section
|
|
|
+ in the documentation, rather than having the documentation in their
|
|
|
+ internal implementation modules.
|
|
|
+ These internal implementation modules are also no longer available
|
|
|
+ to scripts that may have been incorrectly including them, because
|
|
|
+ they should never have been available in the first place.
