CMake 3.13 Release Notes ************************ .. only:: html .. contents:: Changes made since CMake 3.12 include the following. * The :module:`BundleUtilities` module may no longer be included at configure time. This was always a bug anyway. See policy :policy:`CMP0080`. * The :ref:`Makefile Generators` learned to remove custom command and custom target byproducts during ``make clean``. * The new variable :variable:`CMAKE_AUTOGEN_VERBOSE` allows to increase the verbosity of :prop_tgt:`AUTOMOC`, :prop_tgt:`AUTOUIC` and :prop_tgt:`AUTORCC` from within CMakeLists.txt. * The :manual:`cmake ` command gained the ``-S `` command line option to specify the location of the source directory. This option can be used independently of ``-B``. * The :manual:`cmake ` command gained the ``-B `` command line option to specify the location of the build directory. This option can be used independently of ``-S``. * 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. * 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. * The :manual:`cmake(1)` ``-E create_symlink`` command can now be used on Windows. * :manual:`ctest(1)` gained a ``--progress`` option to enable a live test progress summary when output goes to a terminal. * The :command:`add_custom_command` and :command:`add_custom_target` commands learned to support generator expressions in ``WORKING_DIRECTORY`` options. * 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. * 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 the ability to discover Matlab R2018a and R2018b. * The :module:`FindMatlab` module gained a new ``MCC_COMPILER`` component to request finding the Matlab Compiler add-on. * 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 :generator:`Green Hills MULTI` generator is updated: - 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. * The :command:`install(CODE)` and :command:`install(SCRIPT)` commands learned to support generator expressions. * Binary targets gained new :prop_tgt:`INTERFACE_LINK_DEPENDS` property. * The :prop_tgt:`LINK_DEPENDS` target property learned to support :manual:`generator expressions `. * :command:`link_directories` command gains capability to control directories insertion position. * The :prop_tgt:`LINK_DIRECTORIES` target property expects absolute paths. See policy :policy:`CMP0081`. * CMake gained new capabilities to manage link directories: * :prop_tgt:`LINK_DIRECTORIES` and :prop_tgt:`INTERFACE_LINK_DIRECTORIES` target properties. * :command:`target_link_directories` command to add link directories to targets. * CMake gained new capabilities to manage link step: * :prop_dir:`LINK_OPTIONS` directory property. * :prop_tgt:`LINK_OPTIONS` and :prop_tgt:`INTERFACE_LINK_OPTIONS` target properties. * :command:`add_link_options` command to add link options in the current directory. * :command:`target_link_options` command to add link options to targets. * The :command:`list(SORT)` command gained options to control the comparison operation used to order the entries. * The :command:`math` command gained options for hexadecimal. * The :command:`option` command now honors existing normal variables instead of replacing them with a cache entry. See policy :policy:`CMP0077`. * The :command:`target_link_libraries` command may now be called to modify targets created outside the current directory. See policy :policy:`CMP0079`. * Module ``FindPkgConfig`` gains capability to create imported targets in global scope. * static library targets gained new :prop_tgt:`STATIC_LIBRARY_OPTIONS` property. * The :command:`install(TARGETS)` command may now be used to install targets created outside the current directory. * 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:`UseSWIG` module has changed strategy for target naming. See policy :policy:`CMP0078`. * Module ``UseSWIG`` gains capability to manage target property :prop_tgt:`INCLUDE_DIRECTORIES` for ``SWIG`` compilation. * 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 set the debugging environment with :ref:`Visual Studio Generators` for VS 2010 and above. * :prop_tgt:`VS_DEBUGGER_COMMAND` :prop_tgt:`VS_DEBUGGER_COMMAND_ARGUMENTS` :prop_tgt:`VS_DEBUGGER_ENVIRONMENT` :prop_tgt:`VS_DEBUGGER_WORKING_DIRECTORY` target properties can use generator expressions. * 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. * A :variable:`CMAKE_VS_GLOBALS` variable was added to initialize :prop_tgt:`VS_GLOBAL_` target properties on targets as they are created. * 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.
