Downstream distributors can use this to mark a version with their
preferred version information, like a Linux distribution package version
or the Steam revision it was built to be bundled into, or just to mark
it with the vendor it was built by or the environment it's intended to
be used in.
For instance, in Debian I'd use this by configuring with:
--enable-vendor-info="${DEB_VENDOR} ${DEB_VERSION}"
to get a SDL_REVISION like:
release-2.24.1-0-ga1d1946dc (Debian 2.24.1+dfsg-2)
which gives a Debian user enough information to track down the patches
and build-time configuration that were used for package revision 2.
In Autotools and CMake, this is a configure-time option like any other,
and will go into both SDL_REVISION (via SDL_revision.h) and
SDL_GetRevision().
In other build systems (MSVC, Xcode, etc.), defining the
SDL_VENDOR_INFO macro will get it into the output of SDL_GetRevision(),
although not SDL_REVISION.

* Update install directory to match generated
https://github.com/libsdl-org/SDL/blob/main/CMakeLists.txt#L3122
Sets `SDL2Config.cmake` to `CMAKE_BINARY_DIR`, whereas the install file tries to find it from a different location.
* cmake: use CMAKE_CURRENT_BINARY_DIR instead of CMAKE_BINARY_DIR
* ci: test SDL included as a cmake subproject

The official source code release isn't much use unless it contains
everything that users and downstream distributions need to do a
new build, so check that it does.

This is currently only done for the Linux Autotools build. The CMake
build does not add a significant amount of extra test coverage, and
Github Workflows run in an environment where `cmake` and `sudo cmake`
point to different executables, which makes it awkward to install into
/usr/local from CMake.

Some CI workers don't seem to understand `cmake -v`, and Windows' shell
doesn't understand `VERBOSE=1 cmake`.
