llvm 17 now defaults to openmp 5.1; see LLVM commit `0c6f2f629cc0`.
It makes FindOpenMP set OPENMP_FOUND and OpenMP_C_SPEC_DATE, but not
OpenMP_C_VERSION, because it doesn't know the version mapping.
Add the spec date to the version mapping for 5.1 and 5.2 to make
things work again.
Revert commit cf2ad9995a (GetPrerequisites: Ignore relative paths
printed by ldd, 2023-02-20, v3.27.0-rc1~459^2) because it regressed
existing use cases. We will need to find another solution to the use
case motivating the change.
Fixes: #25372
Update the Clang version checks added by
* commit eacacc70fc (Clang: use -std=c++23 for Clang 17.0+,
2023-05-08, v3.27.0-rc1~115^2)
* commit 0183956d30 (Clang: C++26 support,
2023-05-16, v3.27.0-rc1~85^2)
to account for Android NDK r26's distribution of a Clang based on a
development version of LLVM/Clang 17.0 that pre-dated addition of
these flags.
Follow the pattern from commit 12e6796b62 (Android: Do not pass
non-existent Clang -std flags, 2018-04-02, v3.12.0-rc1~284^2),
which fixed the same problem for `-std=c++17`.
Fixes: #25281
Update the list of known versions.
Run the command
cmake -DBOOST_DIR=/path/to/boost_1_83_0 \
-P Utilities/Scripts/BoostScanDeps.cmake
to extract dependencies from the 1.83.0 source tree.
Dependencies differ from 1.82, as mentioned in the 1.83 release notes:
* Boost.Timer no longer depends on Boost.Chrono
Fixes: #25243
Since commit d3c4c6d630 (VS: Import default C++ props file before
toolset-specific props file, 2023-03-01, v3.27.0-rc1~361^2) we import
`Microsoft.Cpp.Default.props` twice. Remove the extra import line, and
re-order imports as intended by the original change.
Fix logic added by commit efa0e2ddaf (FindJNI: Update for Xcode greater than
12.1 on macOS, 2023-08-06, v3.27.2~5^2) to tolerate missing `xcodebuild`.
Fixes: #25181
Since commit 5cc8a69867 (FindOpenSSL: Trust the user's OPENSSL_ROOT_DIR,
2023-05-17, v3.27.0-rc1~71^2) we use `OPENSSL_ROOT_DIR` whenever it is
defined, even if it is an empty string. This breaks a pattern in
existing projects that define an empty `OPENSSL_ROOT_DIR` cache entry so
that `cmake-gui` users can fill it in. Use the value only if non-empty.
Issue: #18352
The lib is named `libnvrtc-builtins.so`, not `libnvrtc_builtins.so`.
Update the change from commit 2a94c762ed (FindCUDAToolkit: Add support
for CUDA::nvrtc_static, 2023-01-20, v3.26.0-rc1~55^2). Apply a fix
similar to commit 9688a8ebc2 (FindCUDAToolkit: Fix
`nvrtc_builtins_static` library name, 2023-02-03, v3.26.0-rc2~15^2).
According to ARMClang documentation 6.20, the patch version number
should not include the last two digits of `__ARMCOMPILER_VERSION`,
which are reserved for internal use by ARM.
Revise the changes from commit fc7dcc6a24 (FindProtobuf: Support new
version number scheme, 2023-06-19, v3.27.0-rc3~2^2). Changing the
content of `Protobuf_VERSION` to exclude the major version of the library
might break code as it can't be used to detect breaking changes in the
library any more.
However, protoc v22 and up don't print the major version any more, so we
need to compare the against a truncated version number, too.
These distros package the hip-lang package under `lib64`, so search it
too. This is similar to commit bae57dc281 (HIP: Fix search for hip-lang
CMake package on multiarch distros, 2023-05-31, v3.27.0-rc1~28^2).
Fixes: #25050
`ExternalProject_Add` treats all keyword arguments as multi-valued.
FetchContent re-orders some keyword arguments w.r.t. unparsed arguments.
Add an internal keyword argument to separate the keyword values from
following unparsed arguments.
This was exposed by commit 550f63447d (ExternalProject/FetchContent:
Support relative remote URLs, 2023-04-21, v3.27.0-rc1~156^2) by adding
`GIT_REPOSITORY` to the set of re-ordered keyword arguments. This
caused its value to absorb following unparsed arguments.
Fixes: #25029
Restore definition of `ANDROID` and `UNIX` when `CMAKE_SYSTEM_VERSION`
is `1`. This was broken by commit 1373373823 (enable_language:
Establish target platform identification variables earlier, 2023-06-06,
v3.27.0-rc1~3^2~1).
Fixes: #25004
Protobuf changed it's version number scheme with version 21. The first number
(usually the major version) is not synchronized between compiler and library
version, but the second and third number are. See
https://protobuf.dev/news/2022-05-06/ for more details.
Fixes: #24847
Since commit 03c6ebf2b5 (Modules:Check,GenerateExportHeader: include
only what's needed, 2023-03-09, v3.27.0-rc1~327^2) some existing
projects broke because they were accidentally relying on indirect
inclusion of some check modules. For now, restore the unnecessary
includes for compatibility. They can be removed with a policy later.
Fixes: #24991
Issue: #24994
Previously we added fallbacks to `llvm-{ar,strip}` on Apple hosts
in case of cross-compiling because the `APPLE` platform variable
was not set w.r.t. the target platform. The platform variable
has been fixed, so remove the fallbacks.
Issue: #23333
Set target platform identification variables like `APPLE` and `LINUX`
as soon as the target system is identified. This makes them available
during toolchain and binutils selection.
Fixes: #23333
Make `CMAKE_LIBRARY_ARCHITECTURE_REGEX` available while determining
compilers before `Platform/{kFreeBSD,GNU}` is loaded.
Follow up commit cc737ae829 (Linux: Provide multiarch library directory
regex earlier, 2023-05-31).
