This is the reason why CMake insists on resolving libraries to complete
paths.  It still can't fix linking to shared libraries, but at least
they can warn/error when you'll be getting a different version than you
asked for.

On the other hand, CMake's approach is spoiled by compilers that have
private paths that you aren't supposed to know about, but that -lsomelib
will be found in.
