Add policy CMP0137 to propagate both our builtin variables and those
listed by `CMAKE_TRY_COMPILE_PLATFORM_VARIABLES` to `try_compile`
whole-project builds.

Fixes: #23219
Add `COMPILE_WARNING_AS_ERROR` target property and supporting
`CMAKE_COMPILE_WARNING_AS_ERROR` variable.
`COMPILE_WARNING_AS_ERROR` is initialized by
`CMAKE_COMPILE_WARNING_AS_ERROR`. It is a boolean variable. If it is
true, it expands to a different flag depending on the compiler such that
any warnings at compile will be treated as errors.
Supports compiler ids that I could find a relevant flag for.
Add a `CMAKE_WATCOM_RUNTIME_LIBRARY` variable to control the
runtime library selection. Add policy CMP0136 to switch to
in place of the old hard-coded default flags.
Fixes: #23178
Allow FetchContent_MakeAvailable() to try a call to
find_package() first, or redirect a find_package() call to
FetchContent_MakeAvailable(). The user can set variables
to control which of these are allowed or tried by default.

Since macOS 12.0 deprecated the tools needed to attach a SLA to a
`.dmg`, we should no longer do this by default. Add a policy to
change the default to off.
Fixes: #22978
The language-specific variable references the general one already,
but the general one did not mention the language-specific one.
Add that cross reference to improve discoverability.
CMake only sets `CMAKE_CACHEFILE_DIR` when writing `CMakeCache.txt`,
so the variable will usually be undefined when `CMakeLists.txt` runs.
Revise its documentation to clarify that `CMAKE_BINARY_DIR` should
be used instead.
Variable CMAKE_LINK_(LIBRARY|GROUP)_USING_<FEATURE>_SUPPORTED is evaluated
only if CMAKE_<LANG>_LINK_(LIBRARY|GROUP)_USING_<FEATURE>_SUPPORTED is not defined.
This new behavior enable to activate a feature globally on a platform and to disable
it for some compilers and languages.
Not all the behaviors of CMake variables for ignoring search
locations by find_...() commands were fully documented.
Add the missing effects, clarify the wording and restructure the
way the details are assembled to reduce duplication.
Also improve the cross-referencing to ensure all the related
variables are more discoverable.
Issue: #20878
Allow find package to promote scope of imported targets by specifying
an argument to `find_package` or by specifying a CMake variable.
* Add support for CMAKE_GLOBAL_IMPORT_SCOPE variable
* Add support for GLOBAL argument to find_package
Additionally add testing for above features.
Add `--test-output-truncation` to `ctest`. This option can be used to
customize which part of the test output is being truncated. Currently
supported values are `tail`, `middle` and `head`.
Also add equivalent `CTEST_CUSTOM_TEST_OUTPUT_TRUNCATION` variable.

The list capability was added in CMake 3.15 by commit fec441ec17 (Teach
CROSSCOMPILING_EMULATOR to support arguments, 2019-05-30,
v3.15.0-rc1~6^2), but the documentation did not indicate the version
that added it.
To be more consistent between genex and variables as well as
the forecomming LINK_GROUP genex, rename variable *_LINK_USING_<FEATURE>*
in *_LINK_LIBRARY_USING_<FEATURE>*
