CMake 3.22.0-rc3 is ready for testing
November 12, 2021
I am proud to announce the third CMake 3.22 release candidate.
https://cmake.org/download/
Documentation is available at:
https://cmake.org/cmake/help/v3.22
Release notes appear below and are also published at
https://cmake.org/cmake/help/v3.22/release/3.22.html
Some of the more significant changes in CMake 3.22 are:
- The “Compile Features” functionality now correctly disables or
enables compiler extensions when no standard level is specified and
avoids unnecessarily adding language standard flags if the requested
settings match the compiler’s defaults. See “CMP0128”. - The “cmake_host_system_information()” command can now query OS
identification variables from the “/etc/os-release” file. - The “CMAKE_BUILD_TYPE” environment variable was added to provide a
default value for the “CMAKE_BUILD_TYPE” variable. - The “CMAKE_REQUIRE_FIND_PACKAGE_<PackageName>” variable was added to
turn a non-REQUIRED “find_package()” call into a REQUIRED one. - The “FetchContent” module now passes through the “CMAKE_TLS_VERIFY”,
“CMAKE_TLS_CAINFO”, “CMAKE_NETRC” and “CMAKE_NETRC_FILE” variables
(when defined) to the underlying “ExternalProject” sub-build.
Previously, those variables were silently ignored by “FetchContent”. - The “Visual Studio 10 2010” generator is now deprecated and will be
removed in a future version of CMake.
CMake 3.22 Release Notes ************************ Changes made since CMake 3.21 include the following. New Features ============ Commands -------- * The "cmake_host_system_information()" command can now query OS identification variables from the "/etc/os-release" file. * The "string(TIMESTAMP)" command now supports the "%V" specifier for ISO 8601 week numbers. Variables --------- * The "CMAKE_BUILD_TYPE" environment variable was added to provide a default value for the "CMAKE_BUILD_TYPE" variable. * The "CMAKE_CONFIGURATION_TYPES" environment variable was added to provide a default value for the "CMAKE_CONFIGURATION_TYPES" variable. * The "CMAKE_INSTALL_MODE" environment variable was added to tell "install()" rules (implemented by "file(INSTALL)") to install symbolic links instead of copying of files. * The "CMAKE_<LANG>_LINK_WHAT_YOU_USE_FLAG" and "CMAKE_LINK_WHAT_YOU_USE_CHECK" variables were added to control the linker flag and check used by the "LINK_WHAT_YOU_USE" target property. * The "CMAKE_REQUIRE_FIND_PACKAGE_<PackageName>" variable was added to turn a non-REQUIRED "find_package()" call into a REQUIRED one. Properties ---------- * The "<LANG>_EXTENSIONS" target property is now initialized to "CMAKE_<LANG>_EXTENSIONS_DEFAULT", detected from the compiler. See "CMP0128". * The "VS_SETTINGS" source file property is now supported for all source file types. Previously it worked only for non-built sources. Modules ------- * The "CMakeDependentOption" module "cmake_dependent_option()" macro now supports full Condition Syntax. See policy "CMP0127". * The "FetchContent" module now passes through the "CMAKE_TLS_VERIFY", "CMAKE_TLS_CAINFO", "CMAKE_NETRC" and "CMAKE_NETRC_FILE" variables (when defined) to the underlying "ExternalProject" sub-build. Previously, those variables were silently ignored by "FetchContent". * The "FindBLAS" and "FindLAPACK" modules gained a "BLA_SIZEOF_INTEGER" option to find a BLAS/LAPACK whose ABI uses a specific integer size. * The "FindJasper" module now provides an imported target. * The "FindMatlab" module now provides imported targets. * The "FindPkgConfig" module gained a "PKG_CONFIG_ARGN" variable to specify arguments to "pkg-config" calls. * The "GoogleTest" module "gtest_discover_tests()" function gained a "TEST_FILTER" option to filter tests using "--gtest_filter" during test discovery. * The "UseSWIG" module, for Visual Studio Generators, can now use the "swig" tool to generate implicit dependencies. CTest ----- * "ctest(1)" learned to recognize labels attached to a test at run time. Previously it was only possible to attach labels to tests at configure time by using the "LABELS" test property. See Additional Test Measurements for more information. * "ctest(1)" learned to be able to modify the environment for a test through the "ENVIRONMENT_MODIFICATION" property. This is allows for updates to environment variables based on the environment present at test time. * The "ctest_memcheck()" command now also generates a "DynamicAnalysis-Test.xml" file which may be used to submit test results to CDash. CPack ----- * The "CPack DEB Generator" gained the option to set "CPACK_DEBIAN_COMPRESSION_TYPE" to "zstd", which enables Zstandard compression for deb packages. * The "CPack NSIS Generator" gained a new "CPACK_NSIS_IGNORE_LICENSE_PAGE" variable to suppress the license page in the installer. * The "CPack RPM Generator" gained the "CPACK_RPM_REQUIRES_EXCLUDE_FROM" option to avoid scanning specific paths for dependencies. Deprecated and Removed Features =============================== * The "Visual Studio 10 2010" generator is now deprecated and will be removed in a future version of CMake. Other Changes ============= * The "Compile Features" functionality now correctly disables or enables compiler extensions when no standard level is specified and avoids unnecessarily adding language standard flags if the requested settings match the compiler's defaults. See "CMP0128". * The "Compile Features" functionality now ignores features for languages that are not enabled. * The Ninja Generators now implement the "edit_cache" target using "ccmake(1)" if available. * The "Ninja" and "NMake Makefiles" generators now use the MSVC "-external:I" flag for system includes. This became available as of VS 16.10 (toolchain version 14.29.30037). * The "CPack NSIS Generator" now requires NSIS 3.03 or later. ---------------------------------------------------------------------------- Changes made since CMake 3.22.0-rc2: Alex Turbov (1): Help: Add `versionadded` for `CPACK_RPM_REQUIRES_EXCLUDE_FROM` variable Ben Boeckel (5): cmCTestRunTest: get the default value from the environment Tests/Environment: also test modifying ambient values FindHDF5: fix variable name when querying `hdf5_hl`'s implib FindHDF5: clear library output variables at the top of the module FindHDF5: clear language-specific libraries list before discovery Brad King (21): MSVC: Refactor C compile features table for C90, C99, and C11 MSVC: Tolerate c_std_17 and c_std_23 features on older compiler versions MSVC: Add support for C17 Help: Fix versionadded for VS 15 2017 instance selection FindMPI: Fix finding PkgConfg for fallback Help: Use lower-case names of sphinx directives cmNinjaTargetGenerator: Replace "their" with "there" in comment Ninja: Fix creation of Windows import library directory GNUtoMS: Add search path for VS 2022 environment scripts cmScanDepFormat: Accept P1689r4 files with version 1 cmGlobalVisualStudio8Generator: Refactor SetGeneratorPlatform Help: Clarify TARGET_RUNTIME_DLLS behavior on imported targets Ninja Multi-Config: Fix cross-config custom command dependency tracing Ninja Multi-Config: Fix internal cross-config target dependency ordering Ninja Multi-Config: Fix custom command target dependencies in cross-configs cmVisualStudio10TargetGenerator: Refactor target framework selection VS: Model a default target framework VS: Default TargetFrameworkVersion to v4.7.2 for VS 2022 gitlab-ci: Re-organize Windows job tags gitlab-ci: Update Windows jobs to VS 2022 CMake 3.22.0-rc3 Craig Scott (4): Help: Clarify how PKG_CONFIG env var initializes cache vars Help: Clarify valid versus supported values for CUDA_STANDARD Help: Correct inaccuracies in wording for CMP0128 TI: Recognize invalid compiler option warning during try_compile() Cristian Adam (2): PCH: Fix REUSE_FROM when Debug and RelWithDebInfo configs differ PCH: Fixed Ninja Multi-Config and REUSE_FROM for MSVC Marc Aldorasi (1): Help: Document that configure_file can create directories Raul Tambre (2): Help: Better explain CMAKE_<LANG>_EXTENSIONS_DEFAULT CMP0128: Enable/disable extensions if standard same as default Robert Maynard (1): NVHPC: Support SYSTEM include directories Thomas Dickerson (1): CheckLinkerFlag: Set policies needed by the implementation William R.
