Ideally find_library would just find the "foo.framework/foo"
library file inside a framework so that the IMPORTED_LOCATION
could be set without constructing that manually.  However, we
have to be compatible with current behavior so that would at
least need to be an option to find_library.  I do not think
a separate find_framework is necessary.

Once the full path to a framework library file inside the
framework directory is known then CMake should pass that to
the linker by full path too instead of using "-framework foo".
