While we already support `VERBOSE` environment variable and
`CMAKE_VERBOSE_MAKEFILE` cached variable, add `-v` and `--verbose`
command line options to be able to activate verbose output directly from
CMake's build tool mode command line.
Also make `msbuild` honor the verbosity setting. `xcodebuild` still
doesn't honor the verbosity setting as it will need a policy added
and reworking of cmGlobalGenerator and cmsys to support
multiple command invocation.
This refactors a std::vector<std::string> into a class so that
we can extend the features to represent things such as multiple
chained commands in the future.

Temporarily restore previous behavior that allowed specifying
no source or build directory to work, even though it was
neither documented nor supported. This commit is expected
to eventually be reverted to restore the fatal error for such
cases.

- CMakeParseImplicitIncludeInfo.cmake: new parser that extracts the
compiler's include path from verbose output. If the parser cannot
parse the output, we fall back to the old behavior. On osx we skip
over framework directories (handled elsewhere).
- CMakeDetermineCompilerABI.cmake:
- use verbose flag in try_compile for ${src}
- use new cmake_parse_implicit_include_info() to attempt extract
implicit include directory path and if successful set
CMAKE_${LANG}_IMPLICIT_INCLUDE_DIRECTORIES
- CMakeCCompiler.cmake.in and CMakeCXXCompiler.cmake.in - preserve
CMAKE_${LANG}_IMPLICIT_INCLUDE_DIRECTORIES value between runs in
the same way CMAKE_${LANG}_IMPLICIT_LINK_DIRECTORIES is preserved
- Tests/RunCMake/ParseImplicitIncludeInfo: tests for parse
based on the older Tests/CMakeTests/ImplicitLinkInfoTest.cmake.in.
The test runs a set of verbose compiler outputs collected from
various machines through the parser and checks the results. New
compiler files can be added by dropping input/output files in the
ParseImplicitIncludeInfo/data subdirectory and then adding the new set
of files to the ${targets} list in ParseImplicitIncludeInfo.cmake.
There is a helper CMakeLists.txt in ParseImplicitIncludeInfo/data
that can help with the generation of test input files.
NOTE: the standard cmake pre-commit hook rejects verbose compiler
output with trailing spaces... you have to manually edit them out.
This shouldn't impact the test.
Note that both the parser and the test code can use CMAKE_${LANG}_COMPILER_*
variables such as ${CMAKE_CXX_COMPILER_ID} to decide how to parse
verbose compiler output. For the test code, this requires us to
save the variables values in the test input files.
Fixes: #16291
Have CMakeDetermineCompilerABI set the locale to C before calling
try_compile(). This is for the implicit include path parser to
keep all the verbose compiler messages in English so we can parse
it. See #18784 for discussion.
Default to the same flag that is used for verbose link information, but
provide another internal platform information variable to use a
compilation-specific variant. Populate it for CUDA where we use a
different compiler for compilation and linking and therefore need
different flags.

When generating the `CMakeLists.txt` file, we pass the values given
to our `COMPILE_DEFINITIONS` option in an `add_definitions` call.
Pass them as bracket arguments to preserve special characters
like `#`.
Add a `CMAKE_PLATFORM_IMPLICIT_INCLUDE_DIRECTORIES` to contain the
hard-coded list of paths to be excluded from `-I` arguments so that the
values remain excluded even if the per-language
`CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES` variants change.
This is needed to preserve our historical exclusion of `-I/usr/include`
even when it is not a real implicit include directory. A policy may be
needed to remove it later.
If CROSSCOMPILING_EMULATOR was set to an empty string, and a test
was generated with the executable as the command, CMake would segfault
upon trying to generate the test file. Fix this.
Fixes: #18819
