Changes made since CMake 3.19 include the following.
|
|
|
|
New Features
|
|
============
|
|
|
|
Presets
|
|
-------
|
|
|
|
* :manual:`cmake-presets(7)` gained support for build and test presets.
|
|
|
|
Generators
|
|
----------
|
|
|
|
* :ref:`Makefile Generators`, for some toolchains, now use the compiler
|
|
to extract implicit dependencies while compiling source files.
|
|
|
|
Languages
|
|
---------
|
|
|
|
* C++23 compiler modes may now be specified via the :prop_tgt:`CXX_STANDARD`,
|
|
:prop_tgt:`CUDA_STANDARD`, or :prop_tgt:`OBJCXX_STANDARD` target properties,
|
|
or via the :manual:`Compile Features <cmake-compile-features(7)>`
|
|
functionality's ``cxx_std_23`` meta-feature.
|
|
|
|
* ``CUDA`` language support now works when ``nvcc`` is a symbolic link,
|
|
for example due to a ``ccache`` or ``colornvcc`` wrapper script.
|
|
|
|
* The :envvar:`CUDAARCHS` environment variable was added for initializing
|
|
:variable:`CMAKE_CUDA_ARCHITECTURES`. Useful in cases where the compiler
|
|
default is unsuitable for the machine's GPU.
|
|
|
|
Compilers
|
|
---------
|
|
|
|
* The NVIDIA HPC SDK compilers are now supported with compiler id ``NVHPC``.
|
|
|
|
* The Intel oneAPI NextGen LLVM compilers are now supported with
|
|
compiler id ``IntelLLVM``:
|
|
|
|
* The ``icx``/``icpx`` C/C++ compilers on Linux, and the ``icx``
|
|
C/C++ compiler on Windows, are fully supported as of oneAPI 2021.1.
|
|
|
|
* The ``ifx`` Fortran compiler on Linux is supported as of oneAPI 2021.1.
|
|
|
|
* The ``ifx`` Fortran compiler on Windows is not yet supported.
|
|
|
|
The Intel oneAPI Classic compilers (``icc``, ``icpc``, and ``ifort``)
|
|
continue to be supported with compiler id ``Intel``.
|
|
|
|
* Support was added for the IAR STM8 compiler.
|
|
|
|
Platforms
|
|
---------
|
|
|
|
* CMake's support for :ref:`Cross Compiling for Android`
|
|
is now merged with the Android NDK's toolchain file.
|
|
They now have similar behavior, though some variable names differ.
|
|
User-facing changes include:
|
|
|
|
- ``find_*`` functions will search NDK ABI / API specific paths by default.
|
|
|
|
- The default :variable:`CMAKE_BUILD_TYPE` for Android is
|
|
now ``RelWithDebInfo``.
|
|
|
|
- The :variable:`CMAKE_ANDROID_NDK_VERSION` variable was added to
|
|
report the version of the NDK.
|
|
|
|
File-Based API
|
|
--------------
|
|
|
|
* The :manual:`cmake-file-api(7)` gained a new "toolchains" object
|
|
kind that describes the compiler used for each enabled language.
|
|
|
|
Commands
|
|
--------
|
|
|
|
* :command:`add_custom_command` and :command:`add_custom_target` now
|
|
support :manual:`generator expressions <cmake-generator-expressions(7)>`
|
|
in their ``OUTPUT`` and ``BYPRODUCTS`` options.
|
|
|
|
Their ``COMMAND``, ``WORKING_DIRECTORY``, and ``DEPENDS`` options gained
|
|
support for new generator expressions :genex:`$<COMMAND_CONFIG:...>` and
|
|
:genex:`$<OUTPUT_CONFIG:...>` that control cross-config handling when using
|
|
the :generator:`Ninja Multi-Config` generator.
|
|
|
|
* The :command:`add_custom_command` command gained ``DEPFILE`` support on
|
|
:ref:`Makefile Generators`.
|
|
|
|
* The :command:`add_library` command previously prohibited imported object
|
|
libraries when using potentially multi-architecture configurations.
|
|
This mostly affected the :generator:`Xcode` generator, e.g. when targeting
|
|
iOS or one of the other device platforms. This restriction has now been
|
|
removed.
|
|
|
|
* The :command:`cmake_path` command was added for operations on
|
|
filesystem paths.
|
|
|
|
* The :command:`configure_file` command gained ``USE_SOURCE_PERMISSIONS``
|
|
and ``FILE_PERMISSIONS`` options to support copying of permissions of the
|
|
source file and using specified permissions respectively.
|
|
|
|
* The :command:`file(GENERATE)` command gained a ``NEWLINE_STYLE`` option to
|
|
specify how newlines are handled for the generated file.
|
|
|
|
* The :command:`file(GENERATE)` command gained ``NO_SOURCE_PERMISSIONS``,
|
|
``USE_SOURCE_PERMISSIONS``, and ``FILE_PERMISSIONS`` options for controlling
|
|
the permissions of the generated file.
|
|
|
|
* The :command:`install(FILES)` command ``RENAME`` option learned to
|
|
support :manual:`generator expressions <cmake-generator-expressions(7)>`.
|
|
|
|
* The :command:`target_include_directories` command gained a new option
|
|
``AFTER``.
|
|
|
|
* The :command:`target_sources` command now supports targets created
|
|
by the :command:`add_custom_target` command.
|
|
|
|
* The :command:`try_run` command gained a ``WORKING_DIRECTORY`` option to
|
|
set the working directory in which to run the compiled check executable.
|
|
|
|
Variables
|
|
---------
|
|
|
|
* The :variable:`CMAKE_<LANG>_BYTE_ORDER` variable was added to provide the
|
|
target architecture byte order detected from the toolchain.
|
|
|
|
* The :variable:`CMAKE_RUNTIME_OUTPUT_DIRECTORY`,
|
|
:variable:`CMAKE_LIBRARY_OUTPUT_DIRECTORY`, and
|
|
:variable:`CMAKE_ARCHIVE_OUTPUT_DIRECTORY` variables now support
|
|
target-dependent generator expressions.
|
|
|
|
Properties
|
|
----------
|
|
|
|
* The :prop_tgt:`<LANG>_CLANG_TIDY` target property and the associated
|
|
:variable:`CMAKE_<LANG>_CLANG_TIDY` variable learned to support
|
|
the ``OBJC`` and ``OBJCXX`` languages.
|
|
|
|
* The :prop_tgt:`EXPORT_COMPILE_COMMANDS` target property was added
|
|
for the associated :variable:`CMAKE_EXPORT_COMPILE_COMMANDS` variable
|
|
to allow for configuration of exporting compile commands per target.
|
|
|
|
* The :prop_sf:`GENERATED` source-file property is now visible
|
|
from any directory scope, regardless of the scope in which it is set.
|
|
See policy :policy:`CMP0118`.
|
|
|
|
* The :prop_tgt:`UNITY_BUILD_UNIQUE_ID` target property
|
|
was added to support generation of an identifier that is
|
|
unique per source file in unity builds. It can help to
|
|
resolve duplicate symbol problems with anonymous namespaces.
|
|
|
|
* The :prop_tgt:`WIN32_EXECUTABLE` target property now works with Clang
|
|
on Windows.
|
|
|
|
* The :prop_tgt:`XCODE_EMBED_FRAMEWORKS <XCODE_EMBED_<type>>` target property
|
|
was added to tell the :generator:`Xcode` generator to embed frameworks.
|
|
Aspects of the embedding can be customized with the
|
|
:prop_tgt:`XCODE_EMBED_FRAMEWORKS_PATH <XCODE_EMBED_<type>>`,
|
|
:prop_tgt:`XCODE_EMBED_FRAMEWORKS_CODE_SIGN_ON_COPY`, and
|
|
:prop_tgt:`XCODE_EMBED_FRAMEWORKS_REMOVE_HEADERS_ON_COPY` target properties.
|
|
|
|
Modules
|
|
-------
|
|
|
|
* The :module:`ExternalData` module :command:`ExternalData_Add_Target`
|
|
function gained a ``SHOW_PROGRESS <bool>`` option for controlling whether
|
|
or not to show progress output during the build.
|
|
|
|
* The :module:`ExternalProject` module :command:`ExternalProject_Add` function
|
|
gained a ``CONFIGURE_HANDLED_BY_BUILD`` option. This can be used to make
|
|
subsequent runs of the configure step be triggered by the build step when
|
|
an external project dependency rebuilds instead of always re-running the
|
|
configure step in such cases.
|
|
|
|
* The :module:`FindBoost` module gained a ``Boost_NO_WARN_NEW_VERSIONS``
|
|
option to silence the warning about unknown dependencies for new
|
|
Boost versions.
|
|
|
|
* The :module:`FindCUDAToolkit` module gained support for finding CUDA
|
|
toolkits when ``nvcc`` is a symbolic link,
|
|
for example due to a ``ccache`` or ``colornvcc`` wrapper script.
|
|
|
|
* The :module:`FindGDAL` module has been improved to document and mark as
|
|
advanced its cache variables. There is a new ``FindGDAL_SKIP_GDAL_CONFIG``
|
|
variable which may be used to skip over the ``gdal-config``-based search.
|
|
Users may also set ``GDAL_ADDITIONAL_LIBRARY_VERSIONS`` to add additional
|
|
versions to the library name search strategy.
|
|
|
|
* The :module:`FindIntl` module now provides an imported target.
|
|
|
|
* The :module:`FindOpenSSL` module learned to support a version range.
|
|
|
|
* The :module:`FindPython3`, :module:`FindPython2` and :module:`FindPython`
|
|
modules gained options controlling how unversioned interpreter names are
|
|
searched.
|
|
|
|
* The :module:`UseJava` module ``add_jar()`` command's
|
|
``GENERATE_NATIVE_HEADERS`` feature gained options to export the
|
|
generated target.
|
|
|
|
* The :module:`UseSWIG` module gained the capability, for
|
|
:ref:`Makefile <Makefile Generators>` and :ref:`Ninja <Ninja Generators>`
|
|
generators, to use the ``swig`` tool to generate implicit dependencies.
|
|
|
|
Autogen
|
|
-------
|
|
|
|
* The :ref:`Qt AUTOMOC` feature now works with per-config sources.
|
|
|
|
CTest
|
|
-----
|
|
|
|
* :manual:`ctest(1)` gained a :option:`--test-dir <ctest --test-dir>`
|
|
option to specify the directory in which to look for tests.
|
|
|
|
CPack
|
|
-----
|
|
|
|
* :module:`CPack` gained the :variable:`CPACK_THREADS` variable to
|
|
control the number of threads used for parallelized operations,
|
|
such as compressing the installer package.
|
|
|
|
* The :cpack_gen:`CPack DEB Generator` learned a new
|
|
:variable:`CPACK_DEBIAN_PACKAGE_SHLIBDEPS_PRIVATE_DIRS`
|
|
variable to specify additional search directories for
|
|
resolving private library dependencies when using
|
|
``dpkg-shlibdeps``.
|
|
|
|
* The :cpack_gen:`CPack IFW Generator` gained a new
|
|
:variable:`CPACK_IFW_PACKAGE_WIZARD_SHOW_PAGE_LIST` variable to
|
|
control visibility of the widget listing installer pages on the left side
|
|
of the wizard. This feature available only since QtIFW 4.0.
|
|
|
|
* The :cpack_gen:`CPack NSIS Generator` gained new
|
|
:variable:`CPACK_NSIS_BRANDING_TEXT` and
|
|
:variable:`CPACK_NSIS_BRANDING_TEXT_TRIM_POSITION` variables to change
|
|
the text at the bottom of the install window and change its trim position
|
|
|
|
* The :cpack_gen:`CPack NSIS Generator` now correctly handles Unicode
|
|
characters. If you want to have a :variable:`CPACK_RESOURCE_FILE_LICENSE`
|
|
with UTF-8 characters, it needs to be encoded in UTF-8 BOM.
|
|
|
|
* The :cpack_gen:`CPack NuGet Generator` gained options:
|
|
|
|
- :variable:`CPACK_NUGET_PACKAGE_ICON` and
|
|
:variable:`CPACK_NUGET_<compName>_PACKAGE_ICON`
|
|
allow package icons to be specified by local files.
|
|
- :variable:`CPACK_NUGET_PACKAGE_LICENSE_EXPRESSION` and
|
|
:variable:`CPACK_NUGET_<compName>_PACKAGE_LICENSE_EXPRESSION` add
|
|
support for specifying licenses recognized by the
|
|
`Software Package Data Exchange`_ (SPDX).
|
|
- :variable:`CPACK_NUGET_PACKAGE_LICENSE_FILE_NAME` and
|
|
:variable:`CPACK_NUGET_<compName>_PACKAGE_LICENSE_FILE_NAME` allow
|
|
licenses to be specified by local files.
|
|
- :variable:`CPACK_NUGET_PACKAGE_LANGUAGE` and
|
|
:variable:`CPACK_NUGET_<compName>_PACKAGE_LANGUAGE` allow the locale
|
|
for a package to be specified, for example ``en_CA``.

|
Deprecated and Removed Features
|
|
===============================
|
|
|
|
* The :manual:`cmake-server(7)` mode has been removed.
|
|
Clients should use the :manual:`cmake-file-api(7)` instead.
|
|
|
|
* The :module:`WriteCompilerDetectionHeader` module has been deprecated
|
|
via policy :policy:`CMP0120`. Projects should be ported away from it.
|
|
|
|
* The :module:`TestBigEndian` module has been deprecated in favor
|
|
of the :variable:`CMAKE_<LANG>_BYTE_ORDER` variable.
|
|
|
|
* The :module:`AddFileDependencies` module is deprecated.
|
|
Port projects to use :command:`set_property` directly.
|
|
|
|
* The :cpack_gen:`CPack NuGet Generator` deprecated some variables to reflect
|
|
changes in the NuGet specification:
|
|
|
|
- :variable:`CPACK_NUGET_PACKAGE_ICONURL` and
|
|
:variable:`CPACK_NUGET_<compName>_PACKAGE_ICONURL` have been deprecated;
|
|
replace with a reference to a local icon file.
|
|
- :variable:`CPACK_NUGET_PACKAGE_LICENSEURL` and
|
|
:variable:`CPACK_NUGET_<compName>_PACKAGE_LICENSEURL` have been deprecated;
|
|
replace with a reference to the project's license file or SPDX
|
|
license expression.
|
|
|
|
Other Changes
|
|
=============
|
|
|
|
* When running :manual:`cmake(1)` to :ref:`Generate a Project Buildsystem`,
|
|
unknown command-line arguments starting with a hyphen (``-``) are now
|
|
rejected with an error. Previously they were silently ignored.
|
|
|
|
* Source file extensions must now be explicit.
|
|
See policy :policy:`CMP0115` for details.
|
|
|
|
* The :prop_sf:`LANGUAGE` source file property now forces compilation
|
|
as the specified language. See policy :policy:`CMP0119`.
|
|
|
|
* On AIX, installation of XCOFF executables and shared libraries
|
|
no longer requires relinking to change the runtime search path
|
|
from the build-tree RPATH to the install-tree RPATH. CMake now
|
|
edits the XCOFF binaries directly during installation, as has
|
|
long been done on ELF platforms.
|
|
|
|
* With MSVC-like compilers the value of
|
|
:variable:`CMAKE_CXX_FLAGS <CMAKE_<LANG>_FLAGS>` no longer contains
|
|
the ``/GR`` flag for runtime type information by default.
|
|
See policy :policy:`CMP0117`.
|
|
|
|
* Ninja generators now transform the ``DEPFILE`` generated by an
|
|
:command:`add_custom_command`. See policy :policy:`CMP0116` for details.
|
|
|
|
* The precompiled Linux binaries provided on
|
|
`cmake.org <https://cmake.org/download/>`_ have changed their naming pattern
|
|
to ``cmake-$ver-linux-$arch``, where ``$arch`` is either ``x86_64`` or
|
|
``aarch64``.
|
|
|
|
* The precompiled Windows binaries provided on
|
|
`cmake.org <https://cmake.org/download/>`_ have changed their naming pattern
|
|
to ``cmake-$ver-windows-$arch``, where ``$arch`` is either ``x86_64`` or
|
|
``i386``.
|
|
|
|
Updates
|
|
=======
|
|
|
|
Changes made since CMake 3.20.0 include the following.
|
|
|
|
3.20.1
|
|
------
|
|
|
|
* The :module:`FindIntl` module in CMake 3.20.0 added checks
|
|
``Intl_HAVE_GETTEXT_BUILTIN``, ``Intl_HAVE_DCGETTEXT_BUILTIN``,
|
|
and ``Intl_IS_BUILTIN``, but they were not implemented correctly.
|
|
These have been removed and replaced with a single ``Intl_IS_BUILT_IN``
|
|
check, whose name is consistent with the :module:`FindIconv` module.
|
|
|
|
* The ``-rpath`` linker flag is now specified as supported on all Apple
|
|
platforms, not just macOS. The ``install_name_dir`` used for
|
|
iOS, tvOS and watchOS should now default to ``@rpath`` instead of using
|
|
a full absolute path and failing at runtime when the library or framework
|
|
is embedded in an application bundle (see :prop_tgt:`XCODE_EMBED_<type>`).
|
|
|
|
3.20.2
|
|
------
|
|
|
|
* The Intel Classic 2021 compiler version numbers are now detected correctly
|
|
as having major version 2021. CMake 3.20.1 and below were not aware of a
|
|
change to the identification macro version scheme made by Intel starting
|
|
in version 2021, and detected the version as 20.2.
|
|
|
|
* The Intel oneAPI Fortran compiler is now identified as ``IntelLLVM``.
|
|
The oneAPI 2021.1 Fortran compiler is missing an identification macro,
|
|
so CMake 3.20.1 and below identified it as ``Intel``. CMake now has
|
|
a special case to recognize oneAPI 2021.1 Fortran as ``IntelLLVM``.
|
|
The oneAPI 2021.2 Fortran compiler defines the proper identification
|
|
macro and so is identified as ``IntelLLVM`` by all CMake 3.20 versions.
|
|
|
|
3.20.3, 3.20.4, 3.20.5, 3.20.6
|
|
------------------------------
|
|
|
|
These versions made no changes to documented features or interfaces.
|
|
Some implementation updates were made to support ecosystem changes
|
|
and/or fix regressions.
|
