CMake Nightly Date Stamp
OSX: Do not add link directories to rpaths.

On Mac OS X, which rpaths to add to a target should be derived from dependent
targets that have an install name using @rpath.  This can be derived if
CMake is given the full path to the library.
Because we need to be restrictive, do not add rpaths for directories
given with link_directories().
