Variable CMAKE_LINK_(LIBRARY|GROUP)_USING_<FEATURE>_SUPPORTED is evaluated
only if CMAKE_<LANG>_LINK_(LIBRARY|GROUP)_USING_<FEATURE>_SUPPORTED is not defined.
This new behavior enable to activate a feature globally on a platform and to disable
it for some compilers and languages.
To be more consistent between genex and variables as well as
the forecomming LINK_GROUP genex, rename variable *_LINK_USING_<FEATURE>*
in *_LINK_LIBRARY_USING_<FEATURE>*
To enable the management of incompatible $<LINK_LIBRARY> declarations,
add LINK_LIBRARY_OVERRIDE and LINK_LIBRARY_OVERRIDE_<LIBRARY> target
properties.
This generator expression offers the capability, for the link step, to
decorate libraries with prefix/suffix flags and/or adding any specific flag for each
library.
