The cost of setting up and executing a separate sub-build to do the
download, update and patch steps required for FetchContent population
can be significant with some platforms and CMake generators. Avoid the
sub-build altogether by invoking the step scripts directly.
Previously, if no generator was set (e.g. population was being done in
script mode), a generator needed to be available on the default PATH.
Since we no longer use a sub-build, this restriction is also now gone.
Fixes: #21703
The mkdir, download, update and patch steps are used by
FetchContent during the configure phase of the main build. Because
these steps need a target, this has so far required a sub-build to be
set up. The changes here factor out the preparation of the scripts
from the creation of the targets, allowing future work to leverage these
steps without a sub-build (see #21703).
As part of the refactoring, some rationalisation of the stamp files,
repository info files and script names was done to make things more
consistent between download methods and step implementations.
Every download method now records its own specific repository info
in a file and that file is a dependency of the download step. The source
directory is also written to that file, so if the SOURCE_DIR changes, the
download will be retriggered (the existing implementation fails in this
scenario). Each download method now also has just one driver script
that implements the whole step (it may pull in other scripts to do its
task though). The patch step gained support for USES_TERMINAL as
a result of generalising the implementation for custom commands.

Using a single ID 'IntelLLVM' for the suite of Intel compilers based on
the LLVM backend. The 'IntelLLVM' ID are used for C, C++, and Fortran.
Data Parallel C++ will be handled in a separate commit.
The C and C++ definitions are based on the Clang definitions. The Intel
LLVM-based C and C++ compilers are based on the Clang front end, so
existing Clang options are more likely to be a good match than options
for the older Intel compilers.
Fortran is based on the older Fortran front end with the LLVM backend.
It has a similar interface to the older versions, though many options
are shared with the C and C++ compilers.

Identify the compilers as `NVHPC` to distinguish it from the older PGI
compilers from which they evolved, and from other `NVIDIA` compilers.

The new CPack variable `CPACK_DEBIAN_PACKAGE_SHLIBDEPS_PRIVATE_DIRS`
can be set to a list of directories. If `CPACK_DEBIAN_PACKAGE_SHLIBDEPS`
or `CPACK_DEBIAN_<component>_PACKAGE_SHLIBDEPS` are set to `ON` these
directories will be searched by `dpkg-shlibdeps` in order to find
private shared library dependencies of the libraries/executables that
shall be packed.
add_custom_command() supports option DEPFILE when generator is
Makefiles or Ninja. And swig tool is able to generate a dependencies
file which is compatible with DEPFILE option.
The `CMAKE_VS_WINDOWS_TARGET_PLATFORM_VERSION_MAXIMUM` variable added in
CMake 3.19 by commit ba497111f6 (VS: Add option for custom Win10 SDK
version maximum, 2020-08-20, v3.19.0-rc1~262^2) was documented as if it
worked for all generators but implemented only to override CMake's
builtin default for the VS 2015 max SDK version. Generalize the
variable to set a custom max SDK version for later VS versions too.
Fixes: #21720
This enables cross-reference syntax for CMake generator expressions:
:genex:`SOME_GENEX`
:genex:`$<SOME_GENEX>`
:genex:`$<SOME_GENEX:...>`
and definition of CMake generator expressions via a directive:
.. genex:: SOME_GENEX
.. genex:: $<SOME_GENEX>
.. genex:: $<SOME_GENEX:...>
It also adds generator expressions defined by the directive and by
`Help/genex/SOME_GENEX.rst` documents to the index.
This was accidentally left out of commit 8acf46caf1 (Utilities/Sphinx:
Add role and directive for 'envvar' in CMake domain, 2018-04-19,
v3.12.0-rc1~200^2~1).
