This enables cross-reference syntax for CMake environment variables:
:envvar:`SOMEVAR`
and definition of CMake environment variables via a directive:
.. envvar:: SOMEVAR
It also adds environment variables defined by the directive and by
`Help/envvar/SOMEVAR.rst` documents to the index.
This `envvar` role and directive is defined in our `cmake` domain
and overrides the equivalent `envvar` role and directive provided
by Sphinx in its default domain. This is okay because we build
CMake documents in the `cmakd` domain.
This follows up the work from commit v3.10.0-rc1~43^2 (Help: Document
CMake's environment variables, 2017-09-01) that originally added
`envvar` documentation.

Previously, only existence of `mfc${v}.dll` and `mfc${v}d.dll` variants
was checked and it was assumed that the managed variants `mfcm*.dll`
also existed. This assumption doesn't hold with Visual Studio 2017.
Check each file separately.
Fixes: #17913
Other check modules honor this variable, so include file checks should
too. Add policy `CMP0075` to enable the behavior in a compatible way.
This change was originally made by commit v3.11.0-rc1~108^2
(CheckIncludeFiles: Honor CMAKE_REQUIRED_LIBRARIES, 2017-12-24) but it
was reverted by commit v3.11.1~9^2 (Revert "CheckIncludeFiles: Honor
CMAKE_REQUIRED_LIBRARIES", 2018-04-04) because the behavior change could
affect checks in existing projects in an incompatible way.
Fixes: #9514
Policies affecting the behavior of CMake-provided macros and functions
need to be able to get the policy setting as of the call site rather
than the definition site. Add an undocumented option to do this.
The OpenWatcom tools do not fail to link when a library is missing if no
symbols were needed from it. This can break `try_compile` checks.
Teach `cmGlobalGenerator::Build` to pretend that the build tool returned
non-zero if the output contains the corresponding warning.
Apple platforms macOS, iOS, tvOS, and watchOS can all share the same
compiler information. Rename `Darwin-*` modules to `Apple-*` and load
them all through `CMAKE_EFFECTIVE_SYSTEM_NAME`. This saves duplication
of 4 * 21 compiler information modules.
Issue: #17870
Create a `CMAKE_EFFECTIVE_SYSTEM_NAME` variable to use for looking
up compiler information modules instead of using `CMAKE_SYSTEM_NAME`
directly. This will allow multiple platforms to share the same set
of compiler information modules without spelling out all of them.
Issue: #17870
Since commit v3.1.0-rc1~565^2~3 (Add platform-specific initialization
step when enabling languages, 2014-04-29) the main enable-language logic
includes the `CMakeSystemSpecificInitialize` module to perform
platform-specific initialization based on `CMAKE_SYSTEM_NAME`. This
should be done during `cmake --find-package` mode too.
The `armeabi` ABI is no longer available, so we can no longer use it by
default unconditionally. Instead detect all available ABIs and choose
the oldest arm ABI that is available.
Also update the test suite to account for the lack of `armeabi` support
and pass as of Android NDK r17-beta2.
