[Fedora-packaging] Moving shared libs to subdirectory

Rawtherapee currently ships two unversioned libs under %{_libdir} and I would like to fix that. Those two libs are only used by Rawtherapee, so I would like to move them under %{_libdir}/rawtherapee. Is it correct to use `-DLIBDIR=%{_libdir}/%{name}` in cmake parameters [1]? Is that all I need to do, or should I also create and ship a custom ld.so.conf.d file as stated in the Guidelines [2]?
