See the :variable:`CMAKE_XCODE_GENERATE_SCHEME` variable. + +* The :generator:`Green Hills MULTI` generator has been 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. + +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. + This option can be used independently of ``-S``. + +* The :manual:`cmake(1)` ``-E create_symlink`` command can now be used + on Windows. + +Commands +-------- + +* The :command:`add_custom_command` and :command:`add_custom_target` commands + learned to support generator expressions in ``WORKING_DIRECTORY`` options. + +* The :command:`add_link_options` command was created to add link + options in the current directory. + +* The :command:`install(TARGETS)` command learned to install targets + created outside the current directory. + +* The :command:`link_directories` command gained options to control + insertion position. + +* 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:`target_link_directories` command was created to + specify link directories for targets and their dependents. + +* The :command:`target_link_options` command was created to + specify link options for targets and their dependents. + +* The :command:`target_link_libraries` command may now be called + to modify targets created outside 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. + +* A :variable:`CMAKE_VS_GLOBALS` variable was added to initialize + :prop_tgt:`VS_GLOBAL_<variable>` target properties on targets as + 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. + +* The :prop_tgt:`INTERFACE_LINK_DEPENDS` target property was created + to specify transitive link dependencies on files. + +* The :prop_tgt:`LINK_DEPENDS` target property learned to support + :manual:`generator expressions <cmake-generator-expressions(7)>`. + +* :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. + +* A :prop_tgt:`STATIC_LIBRARY_OPTIONS` target property was created + 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 + set the debugging environment with + :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. + +* The :module:`FindPkgConfig` module gained support for ``<`` and ``>`` + operators for version checks in addition to the already supported + operators ``>=``, ``<=``, and ``=``. + +* 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 precompiled binaries provided on ``cmake.org`` now include + qthelp-format documentation. + +* The :command:`option` command now honors an existing normal variable + of the same name and does nothing instead of possibly creating a cache + entry (or setting its type) and removing the normal variable. + 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. |
