Since commit f034b0f663 (CMake compilation: do not use compiler
extensions, 2020-03-14, v3.18.0-rc1~494^2), some sources explicitly
enable needed system APIs on some platforms using definitions like
`_POSIX_C_SOURCE` and `_XOPEN_SOURCE`. Drop the definitions for
OpenBSD, which provides the POSIX APIs by default.

This facility is very useful for 'Ninja Multi-Config' and required
as well for future support of DEPFILE in 'Xcode' and 'Visual Studio'
generators (#20286).
This is achieved by adding a rule file which carries the UI files as dependencies but performs no meaningful command. Its output path points to a timestamp file which is instead touched by the pre-build command that runs autogen. The rule file therefore triggers the build if any of the files have been changed more recently than the last autogen run.

Refactoring in commit bdc40742bd (CMakeDetermineCompilerId: Test without
COMPILER_ID_FLAGS if REQUIRE_SUCCESS, 2021-02-27, v3.20.0-rc3~6^2) added
an extra macro layer through which flag strings are passed. That caused
an extra level of argument re-parsing, and broke flags with backslashes.
Pass flags to the helper macro through variable names instead.
Fixes: #22041
Update the change from commit f7f3d8987a (FindBLAS: Add dependency of
OpenBLAS on OpenMP for BLA_STATIC, 2020-11-10, v3.20.0-rc1~492^2):
* If C is not enabled, find CXX OpenMP libraries instead.
* Do not use BLA_STATIC's custom CMAKE_FIND_LIBRARY_SUFFIXES for OpenMP.
It can break projects that already call `find_package(OpenMP)` and
expect a shared library. Whether OpenMP is static is orthogonal to
whether BLAS is static.

Issue: #16221
Since commit 2c71d051fa (Makefiles Generators: use compiler for
dependencies generation, 2020-10-18, v3.20.0-rc1~392^2) we invoke `nvcc`
for CUDA < 10.2 a second time in order to generate a depfile. When
`CMAKE_CUDA_HOST_COMPILER` is set, the second invocation is missing its
`-ccbin=` option, even after refactoring in commit 8981e3e7cc
(NVIDIA-CUDA: rely on new capabilities for deps generation, 2020-12-02,
v3.20.0-rc1~362^2).
Ideally we should move the `-ccbin=` flag into `Compiler/NVIDIA-CUDA`,
but that will add `CMAKE_CUDA_HOST_COMPILER` support on Windows in
command-line generators but not the Visual Studio generators.
For now, add the flag to the depfile command specifically.
