This adds logic to properly handle Swift executables. Only executables
marked as exporting symbols will now generate module interfaces for the
executable.
The `Assembler` test runs the C compiler in a custom command to generate
a `.s` file for the platform. When using the GNU-like Clang variant on
Windows, ensure that the custom command includes the MSVC runtime
library selection flags for Clang. That way the resulting `.s` file,
when assembled into a `.obj`, will tell the linker what runtime library
it needs.
This allows building .s/.S assembly code, and makes sure that the
`-fPIC` option isn't passed to the compiler (as it errors out on
Clang and causes a loud warning on GCC).
If no tests were found, the default behavior of CTest is to always log an
error message but to return an error code in script mode only. This option
unifies the behavior of CTest by either returning an error code if no tests
were found or by ignoring it.

The CPack OSXX11 generator has not had any updates since 2011 except as
part of sweeping maintenance changes. It also creates packages with a
OSXScriptLauncher binary that has only ppc and i386 architectures which
are not supported by Apple anymore. Furthermore, the generator is not
even mentioned in our documentation. Add a deprecation warning.
Fixes: #20235
Since commit 0f150b69d3 (AIX: Explicitly compute shared object exports
for both XL and GNU, 2019-07-11, v3.16.0-rc1~418^2~2) we always export
all symbols from shared libraries by default. Add a new target property
called `AIX_EXPORT_ALL_SYMBOLS` that can be explicitly set to OFF to
suppress this behavior and export no symbols by default.
Fixes: #20290
Since commit f6f4eb0907 (clang-tidy: Add driver mode argument,
2020-01-19) the `clang-tidy` tool rejects the new option:
Unknown command line argument '--driver-mode=g++'.
This is because we are adding the flag before the main compiler
command-line. Encode it with `--extra-arg-before=` so that `clang-tidy`
knows it is supposed to be part of the compiler command.

This is required if MKLROOT points to the subdirectory .../mkl/ instead of
the root of an Intel MKL library installation. Only in this case the MKL
will be searched starting from the parent directory, to detect relevant
dependencies in parallel subdirectories, like 'compiler' and 'tbb'.
In commit 0f150b69d3 (AIX: Explicitly compute shared object exports for
both XL and GNU, 2019-07-11, v3.16.0-rc1~418^2~2) we dropped use of the
old `CMAKE_XL_CreateExportList` cache entry for XL exports. However,
some people were setting the value to an empty string as a way to
disable automatic export of symbols. Restore this behavior when the
option is explicitly set to an empty string.

If a project writes `include(GNUInstallDirs)` before `project()` then
`CMAKE_SYSTEM_NAME` may not be set and an incorrect `LIBDIR` may be
computed. Warn about this case.
Update `_CUDAToolkit_find_and_add_import_lib` to create and add
dependencies to a target in one step that shared a single guard against
repeated definitions. Otherwise we were adding dependencies again on
every call.

In the case that we use ExternalProject_Add to drive the subdirectory
build, replace the `forcebuild` step with the official `BUILD_ALWAYS`
option.
