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.

317a4772 OpenBSD: Fix system feature definitions

Since commit f034b0f6 (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.

9ef82d95 FindBLAS: Fix detection of OpenMP as dependency of BLA_STATIC

Acked-by: Kitware Robot <kwrobot@kitware.com>
Merge-request: !5993

Refactoring in commit bdc40742 (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 f7f3d898 (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.

Fixes: #22039
Issue: #16221

Since commit 2c71d051 (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 8981e3e7
(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.

To avoid starving test jobs, the build jobs should also back off if
there is a lot of machine load.

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.

3538f1c6 Help: Add Q_NAMESPACE_EXPORT to CMAKE_AUTOMOC_MACRO_NAMES default values

Acked-by: Kitware Robot <kwrobot@kitware.com>
Merge-request: !5982

Since CMake 3.19, we no longer support macOS SDKs older than 10.5,
which corresponds to Xcode 3. Supporting older Xcode versions for
device platforms is also not realistic. We therefore expect the -rpath
linker option should always be supported now.

When targeting iOS, tvOS or watchOS, the previous disabling of -rpath
support meant that the install_name_dir of shared libraries and
frameworks was unable to use @rpath. This resulted in embedding
absolute paths for their install_name. When they were embedded in an
app bundle, this would cause the app to fail at runtime. By enabling the
-rpath linker option, the default install_name_dir is now @rpath for these platforms, which results in binaries that do work at runtime.

Fixes: #20036

The NVHPC compiler does not have any implicit link directories that can
be used to detect `CMAKE_LIBRARY_ARCHITECTURE`, but it does have
implicit object files.  Extract implicit object file paths from link
lines and check them for the `CMAKE_LIBRARY_ARCHITECTURE` pattern.
