@farindk Dirk: Please review. Thanks!

@wantehchang I'm not sure about the newly shipped AOMConfig.cmake & friends...

E.g. there is set(AOM_LIBRARIES "aom;aom_static") to support legacy scripts, but why link to both targets simultaneously, seems inappropriate? Should only be "aom" if BUILD_SHARED_LIBS, "aom_static" if not? And I guess these should be "AOM::aom" and "AOM::aom_static"?

See e.g. https://github.com/libsdl-org/sdl2-compat/blob/main/SDL2Config.cmake.in

Also, it would seem the version is not bumped: set(PACKAGE_VERSION "3.12.0") in AOMConfigVersion.cmake

I sent a couple of fixes:

2. https://aomedia-review.googlesource.com/c/aom/+/202782 (AOM_STATIC_LIBRARIES)

Miloš: Could you review the second patch (AOM_STATIC_LIBRARIES) by James? Thanks.

@wantehchang @jzern Thanks you both, looking much better indeed in 3.13.1.
