This diff is collapsed.
CMAKE_FRAMEWORK
---------------
* A :variable:`CMAKE_FRAMEWORK` variable was added to
initialize the :prop_tgt:`FRAMEWORK` property on all
targets.
FindBoost-fphsa
---------------
* The :module:`FindBoost` module was reworked to expose a more
consistent user experience between its config and module modes
and with other find modules in general.
* A new imported target ``Boost::headers`` is now defined (same
as ``Boost::boost``).
* New output variables ``Boost_VERSION_MACRO``,
``Boost_VERSION_MAJOR``, ``Boost_VERSION_MINOR``,
``Boost_VERSION_PATCH``, and ``Boost_VERSION_COUNT``
were added.
* The internal logic for determining the value for
``Boost_FOUND``, for version and component checks, and
for reporting the result to the user was replaced with
the :module:`FindPackageHandleStandardArgs` module. (This
fixed a bug that sometimes printed wrong status
messages in config mode.)
* The ``QUIET`` argument passed to :command:`find_package` is no
longer ignored in config mode.
* *Known issue*: The CMake package shipped with Boost ``1.70.0``
ignores the ``QUIET`` argument passed to :command:`find_package`.
This is fixed in the next Boost release.
* The input switch ``Boost_DETAILED_FAILURE_MSG`` was
removed.
* ``Boost_VERSION`` now reports the version in ``x.y.z``
format in module mode. See policy :policy:`CMP0093`.
FindCups-imported-target
------------------------
* The :module:`FindCups` module now provides imported targets.
FindGLEW-updates
----------------
* The :module:`FindGLEW` module now provides an interface more consistent
with what upstream GLEW provides in its own CMake package files.
FindPostgreSQL-config-support
-----------------------------
* The :module:`FindPostgreSQL` module learned to find debug and release
variants separately.
FindPython-CMP0094
------------------
* Modules :module:`FindPython3`, :module:`FindPython2` and :module:`FindPython`
have changed default strategy for lookup. See policy :policy:`CMP0094`.

-------------------------
* Modules :module:`FindPython3`, :module:`FindPython2` and :module:`FindPython`
gain a new variable to control frameworks lookup on macOS.
FindPython-FIND_STRATEGY
------------------------
* Modules :module:`FindPython3`, :module:`FindPython2` and :module:`FindPython`
gain a new way to control lookup strategy.
FindPython-module
-----------------
* Modules :module:`FindPython`, :module:`FindPython2` and :module:`FindPython3`
gain a new target (respectively ``Python::Module``, ``Python2::Module``
and ``Python3::Module``) which can be used to develop Python modules.
FindPython-virtual-env
----------------------
* Modules :module:`FindPython3`, :module:`FindPython2` and :module:`FindPython`
gain capability to control how virtual environments are handled.
UseSWIG-alternate-library-name
------------------------------
* The :module:`UseSWIG` module learned to manage alternate library names by
passing ``-interface <library_name>`` for ``python`` language or
``-dllimport <library_name>`` for ``CSharp`` language to the ``SWIG``
compiler.
add-execute_process-command-echo
--------------------------------
* The :command:`execute_process` command gained a `COMMAND_ECHO` option
and supporting :variable:`CMAKE_EXECUTE_PROCESS_COMMAND_ECHO` variable
to enable echoing of the command-line string before execution.
add-xlclang
-----------
* IBM Clang-based XL compilers that define ``__ibmxl__`` now use the
compiler id ``XLClang`` instead of ``XL``. See policy :policy:`CMP0089`.
additional_clean_files
----------------------
* New target property :prop_tgt:`ADDITIONAL_CLEAN_FILES` and directory property
:prop_dir:`ADDITIONAL_CLEAN_FILES` were added. They allow to register
additional files that should be removed during the clean stage.
* Directory property :prop_dir:`ADDITIONAL_MAKE_CLEAN_FILES` was marked
deprecated. The new directory property :prop_dir:`ADDITIONAL_CLEAN_FILES`
should be used instead.
allow-aliasing-unkown-import-targets
------------------------------------
* :command:`add_library` command ``ALIAS`` option learned to support
import libraries of the ``UNKNOWN`` type.
apple-clang-supports-cxx20
--------------------------

----------------------------
* The :manual:`cmake(1)` ``--build`` tool ``--target`` parameter gained support for
multiple targets, e.g. ``cmake --build . --target Library1 Library2``.
cmake-e-tar-creating-archive
----------------------------
* The :manual:`cmake(1)` ``-E tar`` tool now continues adding files to an
archive, even if some of the files aren't readable. This behavior is more
consistent with the classic ``tar`` tool.
cmake-e-tar-error-handling
--------------------------
* The :manual:`cmake(1)` ``-E tar`` tool now parses all flags, and if an
invalid flag was provided, a warning is issued.
* The :manual:`cmake(1)` ``-E tar`` tool now displays an error if no action
flag was specified, along with a list of possible actions: ``t`` (list),
``c`` (create) or ``x`` (extract).
cmake-e-tar-extract-specific-files
----------------------------------
* The :manual:`cmake(1)` ``-E tar`` tool allow for extract (``-x``) or list
(``-t``) only specific files or directories. To select pathnames append
a space-separated list of file names or directories.
When extracting selected files or directories, you must provide their exact
pathname, as printed by list (``-t``)
Help/release/dev/cmake-e-tar-zstd-support
-----------------------------------------
* The :manual:`cmake(1)` ``-E tar`` tool now support Zstandard compression
algorithm with ``--zstd`` option. Zstandard was designed to give
a compression ratio comparable to that of the DEFLATE (zip) algorithm,
but faster, especially for decompression.
cmake-short-target-option
----------------------------
* The :manual:`cmake(1)` ``--target`` parameter gained shorter
version ``-t``, e.g. ``cmake --build . -t Library1 Library2`` is
equivalant to ``cmake --build . --target Library1 Library2``.
cmake_automoc_relaxed_mode
--------------------------
* The variable :variable:`CMAKE_AUTOMOC_RELAXED_MODE` is considered
deprecated. Support still exists but will be removed in future versions.

----------------------------
* The :cpack_gen:`CPack IFW Generator` gained a new
:variable:`CPACK_IFW_PACKAGE_STYLE_SHEET` variable to customize the
installer stylesheet.

* The :command:`ctest_update` command learned to honor a new variable:
:variable:`CTEST_UPDATE_VERSION_OVERRIDE`. This can be used to specify
the current version of your source tree rather than using the update
command to discover the current version that is checked out.
cuda-compiler-generator-expressions
-----------------------------------
* The ``$<CUDA_COMPILER_ID:...>`` and ``$<CUDA_COMPILER_VERSION:...>``
:manual:`generator expressions <cmake-generator-expressions(7)>` were added.

to specify a default generator to use when :manual:`cmake(1)` is
run without a ``-G`` option. Additionally, environment variables
:envvar:`CMAKE_GENERATOR_PLATFORM`, :envvar:`CMAKE_GENERATOR_TOOLSET`,
and :envvar:`CMAKE_GENERATOR_INSTANCE` were created to configure
the generator.
deprecate-policy-old
--------------------
* An explicit deprecation diagnostic was added for policy ``CMP0066``
(``CMP0065`` 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
