CMAKE_<LANG>_LINKER_PREFERENCE
------------------------------

Preference value for linker language selection.

The "linker language" for executable, shared library, and module
targets is the language whose compiler will invoke the linker.  The
LINKER_LANGUAGE target property sets the language explicitly.
Otherwise, the linker language is that whose linker preference value
is highest among languages compiled and linked into the target.  See
also the CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES variable.
