Craig Scott cbb87e0a2c ExternalProject: Add support for USES_TERMINAL_PATCH keyword
This brings the patch step into line with all the others which already
had their own `USES_TERMINAL_<step>` keyword. All steps (including
patch) already have their own `LOG_<step>` keyword too, so the lack of
`USES_TERMINAL_PATCH` was inconsistent.

CMake 3.23 Release Notes
************************
.. only:: html
.. contents::
Changes made since CMake 3.22 include the following.
New Features
============
Presets
-------
* :manual:`cmake-presets(7)` files now support schema version ``4``.
* :manual:`cmake-presets(7)` files now have an optional ``include`` field,
which allows the files to include other files.
* :manual:`cmake-presets(7)` gained support for specifying the
``resolvePackageReferences`` command line option in a build preset.
Generators
----------
* The :ref:`Visual Studio Generators` for VS 2019 and above learned to
support .NET SDK-style project files (``.csproj``) for C# projects.
See the :prop_tgt:`DOTNET_SDK` target property and corresponding
:variable:`CMAKE_DOTNET_SDK` variable. :command:`add_custom_command`
is not yet supported in .NET SDK-style projects.
* The :ref:`Visual Studio Generators` for VS 2017 and above learned to
use portable instances of Visual Studio not known to the VS installer.
See the :variable:`CMAKE_GENERATOR_INSTANCE` variable.
Command-Line
------------
* The :manual:`cmake(1)` ``--build`` command, when used with
:ref:`Visual Studio Generators` on projects that set the
:prop_tgt:`VS_PACKAGE_REFERENCES` target property, now automatically
restores package references from NuGet. The cache variable
:variable:`CMAKE_VS_NUGET_PACKAGE_RESTORE` may be set to toggle this behavior
in a build tree. Use the ``--resolve-package-references=<on|off|only>``
command-line option to control the behavior on one invocation.
* The :manual:`cmake(1)` command line tool gained a ``--debug-find-pkg=``
option to enable debug messages under specific :command:`find_package`
calls.
* The :manual:`cmake(1)` command line tool gained a ``--debug-find-var=``
option to enable debug messages for ``find_*`` calls that use specific
result variables.
Compilers
---------
* The IBM Open XL C/C++ compiler, based on LLVM, is now supported with
compiler id ``IBMClang``.
* The MCST LCC compiler is now supported with compiler id ``LCC``.
See policy :policy:`CMP0129`.
File-Based API
--------------
* The :manual:`cmake-file-api(7)` "codemodel" version 2 ``version`` field
has been updated to ``2.4``.
* The :manual:`cmake-file-api(7)` "codemodel" version 2 ``directory``
object ``installers`` field gained a new ``fileSet`` installer type.
Commands
--------
* The :command:`define_property` command gained a new
``INITIALIZE_FROM_VARIABLE`` option to cause a target property to be
initialized from a variable when a target is created.
* The :command:`install(TARGETS)` command gained a new ``FILE_SET`` argument,
which can be used to install header file sets associated with a target.
* The :command:`string(TIMESTAMP)` and :command:`file(TIMESTAMP)` commands now
support the ``%f`` specifier for microseconds.
* The :command:`target_sources` command gained a new ``FILE_SET`` mode, which
can be used to add headers as header-only source files of a target.
Variables
---------
* The :variable:`CMAKE_CUDA_ARCHITECTURES` variable and associated
:prop_tgt:`CUDA_ARCHITECTURES` target property now support the
``all``, and ``all-major`` values for CUDA toolkit 7.0+.
* The :variable:`CMAKE_IGNORE_PREFIX_PATH` and
:variable:`CMAKE_SYSTEM_IGNORE_PREFIX_PATH` variables were added
to tell the :command:`find_package`, :command:`find_program`,
:command:`find_library`, :command:`find_path`, and :command:`find_file`
commands to ignore specified prefixes.
* The :variable:`CMAKE_LINK_LIBRARIES_ONLY_TARGETS` variable and
corresponding :prop_tgt:`LINK_LIBRARIES_ONLY_TARGETS` target
property were added to optionally require that all link items
that can be target names are actually names of existing targets.
Properties
----------
* The :prop_tgt:`HEADER_SETS` and :prop_tgt:`INTERFACE_HEADER_SETS` target
properties were added to list header sets associated with a target.
* The :prop_tgt:`HEADER_SET` and :prop_tgt:`HEADER_SET_<NAME>` target
properties were added to list files in the default header set
and named header sets, respectively.
* The :prop_tgt:`HEADER_DIRS` and :prop_tgt:`HEADER_DIRS_<NAME>` target
properties were added to specify the base directories of the default
header set and named header sets, respectively.
* The :prop_tgt:`IMPORTED_NO_SYSTEM` target property was added to
specify that an :ref:`Imported Target <Imported Targets>` should
not be treated as a system library (i.e. its include directories
are not automatically ``SYSTEM``).
* The :prop_tgt:`INTERFACE_LINK_LIBRARIES_DIRECT` and
:prop_tgt:`INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE` target properties
were added to express usage requirements affecting a consumer's
direct link dependencies.
* The :prop_tgt:`XCODE_EMBED_PLUGINS <XCODE_EMBED_<type>>` target property
was added to tell the :generator:`Xcode` generator what targets to put in
the ``Embed PlugIns`` build phase.
* The :prop_tgt:`XCODE_SCHEME_ENABLE_GPU_FRAME_CAPTURE_MODE` target property
and supporting :variable:`CMAKE_XCODE_SCHEME_ENABLE_GPU_FRAME_CAPTURE_MODE`
variable were added to tell the :generator:`Xcode` generator to enable
specifying the Xcode scheme option property ``GPU Frame Capture``.
Modules
-------
* The :module:`CheckPIESupported` module now supports the ``OBJC``,
``OBJCXX``, ``CUDA``, and ``HIP`` languages. It also now honors
:variable:`CMAKE_SYSROOT` and :variable:`CMAKE_OSX_SYSROOT`.
* The :module:`ExternalProject` module's :command:`ExternalProject_Add`
command gained support for a ``USES_TERMINAL_PATCH`` option to give
the patch step exclusive terminal access.
* The :module:`FindCUDAToolkit` module now provides a target for
``libcufft_static_nocallback``, if found.
* The :module:`FindGLUT` module now provides the ``GLUT_INCLUDE_DIRS``
result variable to conform with naming conventions documented in the
:manual:`cmake-developer(7)` manual. This supersedes the legacy
``GLUT_INCLUDE_DIR`` variable.
* The :module:`FindGTest` module now provides a target for GMock, if found.
* The :module:`FindVulkan` module now provides a ``Vulkan_VERSION`` result
variable reporting the version number.
CTest
-----
* :manual:`ctest(1)` gained a new :variable:`CTEST_SUBMIT_INACTIVITY_TIMEOUT`
variable, which can be used to specify a timeout for submission inactivity.
CPack
-----
* The :cpack_gen:`CPack productbuild Generator` gained the new
:variable:`CPACK_PRODUCTBUILD_DOMAINS`,
:variable:`CPACK_PRODUCTBUILD_DOMAINS_ANYWHERE`,
:variable:`CPACK_PRODUCTBUILD_DOMAINS_USER`, and
:variable:`CPACK_PRODUCTBUILD_DOMAINS_ROOT` variables for
adding the domains element to the Distribution XML.
* The :cpack_gen:`CPack productbuild Generator` gained a new variable,
:variable:`CPACK_PRODUCTBUILD_IDENTIFIER`, used to customize the unique
product identifier associated with the product.
* The :cpack_gen:`CPack IFW Generator` gained the new
:variable:`CPACK_IFW_ARCHIVE_FORMAT` and
:variable:`CPACK_IFW_ARCHIVE_COMPRESSION` variables for setting the
format used when packaging new component data archives, and choosing
the compression level used.
These features are available for QtIFW 4.2 and newer.
* The :cpack_gen:`CPack IFW Generator` gained new
:variable:`CPACK_IFW_PACKAGE_DISABLE_COMMAND_LINE_INTERFACE` variable to
prevent the user from passing any consumer command to the installer, like
``install``, ``update``, and ``remove``.
This feature is available for QtIFW 4.0 and newer.
* The :cpack_gen:`CPack IFW Generator` gained the new
:variable:`CPACK_IFW_PACKAGE_PRODUCT_IMAGES` variable for adding a
list of images to be shown on the ``PerformInstallationPage``.
This feature is available for QtIFW 4.0 and newer.
* The :cpack_gen:`CPack IFW Generator` gained the new
:variable:`CPACK_IFW_PACKAGE_RUN_PROGRAM`,
:variable:`CPACK_IFW_PACKAGE_RUN_PROGRAM_ARGUMENTS`, and
:variable:`CPACK_IFW_PACKAGE_RUN_PROGRAM_DESCRIPTION` variables for
executing a command after the installer is done if the user accepts
the action. This feature is available for QtIFW 4.0 and newer.
* The :cpack_gen:`CPack IFW Generator` gained the new
:variable:`CPACK_IFW_PACKAGE_SIGNING_IDENTITY` variable for specifying a
code signing identity to be used for signing the generated app bundle.
This feature is available on macOS only, and for QtIFW 3.0 and newer.
* The :cpack_gen:`CPack WIX Generator` gained a new variable,
:variable:`CPACK_WIX_SKIP_WIX_UI_EXTENSION`, to skip the inclusion
of WixUIExtensions.
Deprecated and Removed Features
===============================
* The :manual:`cpack(1)` undocumented ``OSXX11`` generator has been removed.
Other Changes
=============
* The :cpack_gen:`CPack DragNDrop Generator` no longer attaches
:variable:`CPACK_RESOURCE_FILE_LICENSE` as the license agreement in
the generated ``.dmg`` unless explicitly activated by a
:variable:`CPACK_DMG_SLA_USE_RESOURCE_FILE_LICENSE` option.
In CMake projects, the :module:`CPack` module enables the option
by default for compatibility.
* ``CUDA`` targets may now enable both :prop_tgt:`CUDA_SEPARABLE_COMPILATION`
and :prop_tgt:`CUDA_PTX_COMPILATION`.
* ``CUDA`` compiler detection now:
* issues an error in all cases when it's unable to compute the default
architecture(s) if required (see :policy:`CMP0104`),
* handles ``OFF`` for :variable:`CMAKE_CUDA_ARCHITECTURES` on Clang,
* supports the theoretical case of multiple default architectures, and
* tries to detect invalid architectures and issue an error.
* ``CUDA`` with Clang now implements policy :policy:`CMP0105` and
the ``$<DEVICE_LINK:...>`` and ``$<HOST_LINK:...>``
:manual:`generator expressions <cmake-generator-expressions(7)>`.
* The :command:`define_property` command's ``BRIEF_DOCS`` and ``FULL_DOCS``
arguments are now optional.
* :manual:`ccmake(1)` may now be enabled on Windows when building
CMake from source. This is experimental, and so is not included
in official distributions.
