Add a new `--trace-format=` flag, to enable the new JSON trace
output format. This new format is easier to parse by machines
than the existing format. This new format also removes the
ambiguity of the whitespace in the "old" format (e.g. is that
whitespace part of a file path, or does it seperate arguments)
Enable debug messages a new `--find-debug` command-line option or via
the `CMAKE_FIND_DEBUG_MODE` variable.
This work was started by Chris Wilson, continued by Ray Donnelly, and
then refactored by Robert Maynard to collect information into a single
message per find query.

An old workaround for `std::allocator_traits<>::value_type` lints from
IWYU on `std::vector<>` usage breaks IWYU's handling of `<memory>`.
Convert the workaround to use the same approach we already use for a
workaround of `std::__decay_and_strip<>::::__type` lints. Then update
the `<memory>` inclusions to follow the now-correct IWYU lints.
The `cmake -E capabilities` command-line tool is implemented only in a
full-featured (non-bootstrap) CMake, and server mode is now always
available in this case.
When there is no Generator available in the Cache, this will read
CMAKE_GENERATOR from environment before using the CMake platform default.
If CMAKE_GENERATOR is empty, use the platform default.
If a environment default generator is specified, subsequent variables
CMAKE_GENERATOR_(INSTANCE,PLATFORM,TOOLSET) are also evaluated
in the same way.

* The `InTryCompile` member has been unused since commit 62854e9966
(cmState: Move try_compile state from cmake class., 2015-04-11,
v3.3.0-rc1~196^2~9).
* The `ConvertMessageType` and `IsMessageTypeVisible` members have been
unused since commit 421012a330 (cmMessenger: Extract from cmake class,
2016-01-28, v3.7.0-rc1~222^2~1).
* The `InitializeProperties` member has been unused since commit

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.
Required extracting default generator evaluation
to explicit function, as Visual Studio generators
get validated during their construction.
Fixes: #18544
The GetGeneratorDocumentation() function was not accurately
named and required the vector to populate to be passed as a
function argument. This commit makes the slightly renamed
function return by value, making it a true getter as implied
by its name. Some minor refactoring of the implementation
also makes the steps of populating the vector clearer.
Add a `cmGlobalGeneratorFactory::GetKnownPlatforms` method to return
a list of known possible values for `CMAKE_GENERATOR_PLATFORM`.
Implement the method for each generator by referencing the list of
possible values documented in `Help/generator/*.rst` for it.

Replace `cmGlobalGeneratorFactory::GetGenerators` with a pair of methods
to split the list of generator names into those that have platforms in
the name and those that do not.
27eb7c5bdb cmake: Ensure source and binary dirs are set
a1adbc7243 cmake: Stop processing if -P option lacks file name
Acked-by: Kitware Robot <kwrobot@kitware.com>

If only the source dir is provided, the binary dir is assumed
to be the working directory. If only the binary dir is provided
and it doesn't yet have a CMakeCache.txt to provide the
source dir, then the source dir is assumed to be the working
directory. This logic was not previously being handled
correctly when -S and/or -B options were involved.
Furthermore, when both were missing, no suitable error
message was provided and an empty string was used for
the build directory.
Fixes: #18707
Add a file-based API that clients may use to get semantic information
about the buildsystem that CMake generates. Clients will write query
files under a designated location in the build tree, and CMake will
write reply files for clients to read.
Start with support for shared stateless query files. These allow
clients to share requests for major object versions and get all those
recognized by CMake. Once any client has written a shared request to a
build tree it will persist. Other clients will not need to overwrite
the request (since it is stateless) and should not remove it either.
For now we add only an undocumented object kind to use for testing the
query and reply infrastructure. Object kinds providing real semantic
information will be added later.
Issue: #18398
