Since commit a7f41a7ee4 (Android: Fix find_* search order within NDK for
unified toolchains, 2020-10-13, v3.20.0-rc1~610^2), we turn off
`CMAKE_FIND_USE_SYSTEM_ENVIRONMENT_PATH`. This breaks `find_program`
searching `PATH` for host executables. Fortunately, the setting turns
out not to be necessary, perhaps since commit cbc51a8be3 (Android:
restructure android search paths, 2020-11-06, v3.20.0-rc1~509^2).
Without it, none of NDK tests fail, so remove it to restore pre-3.20
behavior.
Fixes: #22634
Since commit 5b9bfe738c (IAR: Moved search logic to BinUtils.,
2021-07-19, v3.21.1~14^2), we use the `IN_LIST` operator in the
`CMakeFindBinUtils` module. Set policy `CMP0057` to ensure it is
available regardless of the project's policy settings.
Fixes: #22640
Backport KWSys commit `4ef5b1063` (SystemTools: Ensure Windows Vista
APIs are available before using them, 2021-08-30) to the CMake 3.21
release branch.
This was forgotten in commit 0c7f918fb1 (VS: Update Visual Studio 17
2022 generator for Preview 2, 2021-07-14, v3.21.1~29^2) when the toolset
was first renumbered to `v143`.
Fixes: #22585
Update the list of known versions.
Run the command
cmake -DBOOST_DIR=/path/to/boost_1_77_0 \
-P Utilities/Scripts/BoostScanDeps.cmake
to extract dependencies from the 1.77.0 source tree. The dependencies
differ from those of 1.76: the `contract`, `thread`, and `wave`
components no longer depend on `date_time`. The `math` component no
longer depends on `atomic`.
Fixes: #22588
In some situations, it seems that the variable `0` is defined. In the
case found, it was set to `1`. This makes the detection of the missing
third argument bogus and unnecessarily triggers a warning.
This oversight was introduced in 229b5ee994 (GNUInstallDirs: Add dir
argument to GNUInstallDirs_get_absolute_install_dir, 2020-10-31) prior
to CMake 3.20's release cycle.
Extend the table of special cases from commit 58a50a3a0a (VS: Fix '-T
version=14.28' under VS 16.9, 2021-03-11, v3.19.7~1^2~1) and updated by
commit a60141feaa (VS: Add special case for '-T version=14.29.16.10'
under VS 16.10, 2021-05-27, v3.20.4~11^2). Add a special case for the
name VS 17 will use for VS 16.11's default toolset, so that it can be
used with VS 16.11 too.
Issue: #21922
MPICH 3.4.2 now reports `-framework OpenCL` as one of its compilation
flag. The compile flag extraction is seeing it as a generic `-f` flag
and misses its argument. This ends up with a compile option of
`-framework` which eats the next flag (and may be very important).
It does not seem that passing `-framework` as a link flag is necessary
at this time, so that is being actively ignored for now.
Fixes: #22555
Revert commit e5ec0e52f4 (AUTOUIC: Fix generating of dependency rules
for UI header files, 2021-07-22, v3.21.1~8^2) because it caused
regressions. For example, changing one C++ source can now cause many
others to rebuild. Revert the change pending further investigation.
Fixes: #22531
Issue: #16776
The macro's implementation converts a normal variable into a cache
variable intentionally, so both are set. Explicitly set CMP0126 to NEW
to avoid a warning in trace mode. This won't affect the module behavior
because the code path does not activate if a normal variable is already
defined anyway.
Fixes: #22548
Our `find_program` calls specify `HINTS` to look in the toolchain's
directory first, and then in `PATH`. `CMAKE_PREFIX_PATH` may be
specified by the user to help find packages for project dependencies,
but this should not override the binutils.
Fixes: #22512
