[CMake] Full absolute path as RPATH in build tree

[Michael Jackson]

what combinations of RPATH variables do I need to set to get a full, 
absolute path to a build library in my build tree? THis is on macOS 
10.10.5 and cmake 3.5 and above. I have tried all sorts of combinations 
and I either get just the library name or @rpath/library.dylib neither 
of which is going to work for my needs.

Thanks
