[CMake] Adding dylib with either @rpath or absolute paths to osx cmd line executable target

[Clinton Stimpson]

Have you looked at using "install_name_tool -id" to change the id of the 
shared library.

If you do install_name_tool -id @rpath/libiomp5.dylib /path/to/libiomp5.dylib

Then when you link dylibLinkTest and then check it with otool -L, it will 
already have "@rpath/libiomp5.dylib" instead of just a plain "libiomp5.dylib"
With that, there will be no need to constantly fix your executables with 
install_name_tool each time you link.

BundleUtilities pulls all the dependencies into a bundle and uses 
@executable_path.  BundleUtilities does not support @rpath, except that it is 
recognized and changed to @executable_path.
