Since commit f65f20938c (Autogen: Avoid processing CSharp targets,
2020-11-12, v3.20.0-rc1~301^2) we collect all sources for a target
earlier than previously. Clear the sources cache so that it will be
re-computed later after AUTOGEN processing.

6234afdff4 Help: Document special cases for if(IS_ABSOLUTE)
789307b02f Help: Behavior of file(TO_NATIVE_PATH) depends on the host platform

The meaning of "absolute path" was previously assumed knowledge,
but a number of special cases were left unspecified. The way some of
these are handled differs to the way that cmake_path(IS_ABSOLUTE)
works, so document those special cases so that the differing behavior
between these two commands is clearly defined.
When running a pipeline on an integration branch in `cmake/cmake`, delay
the lint jobs just as much as all the others. This avoids starting them
unnecessarily during a sequence of merges over a short time range.
Since commit b12aec6c8d (BinUtils: prefer bin utils matching the
compiler version extension, 2020-12-11, v3.20.0-rc1~171^2) we recognize
`clangg++` and `g++` but not `c++`. Restore `[gc]` in place of `g`
in the regex, as we had before that change.
Fixes: #22069
cmReadGccDepfile() calls cmSystemTools::CollapseFullPath(), which
is not thread safe due to internal caching. Serialize calls to
cmReadGccDepfile() in autogen to avoid thread safety issues.

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.
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.
Fixes: #22037
Refactoring in commit b12aec6c8d (BinUtils: prefer bin utils matching
the compiler version extension, 2020-12-11, v3.20.0-rc1~171^2)
accidentally leaked a `TOOL` variable. Name temporary variables with a
private prefix.
Fixes: #22035
CMake's test suite is sensitive to machine load and can cause spurious
timeouts. To acknowledge this, prevent CTest from spawning tests into a
busy machine.
