In commit 5bc6230741 (ExternalProject: Option to turn off recursive
update of git submodules, 2019-10-16) we implemented the feature in the
clone script written by `_ep_write_gitclone_script` but not in the
update script written by `_ep_write_gitupdate_script`. Implement the
latter by factoring out a common helper to use in both places.

The fix in commit 5861c6d450 (FindMPI: Preserve include order when
extracting component directories, 2019-12-19) only works on the first
run of CMake in which we find MPI. Extend the fix to save the compiler
wrapper's entire include path in our cache without splitting anything
out. That way we can preserve the order when CMake re-runs.

The fix in commit 5861c6d450 (FindMPI: Preserve include order when
extracting component directories, 2019-12-19) only works on the first
run of CMake in which we find MPI. It preserves the include directories
on the first run but still splits them up and saves the pieces in the
cache. On future runs the pieces are not re-assembled, and we do not
know the order anyway.
Restore the re-assembly step so that at least all the include dirs are
available. Leave preservation of the original order to later work.

Populate `CMAKE_Swift_IMPLICIT_INCLUDE_DIRECTORIES` with the macOS SDK's
include directory so that we filter such implicit directories out of
Swift targets.

llvm-rc requires preprocessed rc files. The CMake command line tool
cmake_llvm_rc enables channing the preprocessor call and the resource
compiler and make this appear as single compilation step.
When llvm-rc is detected as resource compiler, the RC compilation step
is set to use this command.
Simply remove `-Werror` flags from `CMAKE_<LANG>_FLAGS` to avoid failing
ABI detection if there happen to be warnings in the test project. For
example, `-Wunused-command-line-argument` warnings are common since the
ABI detection project may not exercise all the flags passed by users.
Fixes: #20305
CMake properly detects the toolkit directories as implicit system
includes, but CUDA compilers don't add explicit `-isystem` markups to
these directories when compiling CUDA code. Due to this limitation,
allow users to explicitly specify these directories as SYSTEM dirs.
Fixes: #16464, #19864
In commit 97bca2f9fa (Android: Use unified toolchain in NDK r19+,
2019-07-26, v3.16.0-rc1~342^2) we hard-coded use of the unified
toolchain for NDK r19+ and skipped most of the old detection logic.
However, in that fast path we left out setting `_CMAKE_TOOLCHAIN_PREFIX`
for `CMakeFindBinutils` to select the matching binutils. Add it.

This adds logic to properly handle Swift executables. Only executables
marked as exporting symbols will now generate module interfaces for the
executable.
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).
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
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.
Issue: #20290
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.
