It's not clear whether you are saying this works or asking how to get it 
to work.

For the executable in the build tree you have the choice of either the 
current rpath or no rpath at all (set the SKIP_BUILD_RPATH property). 
For the executable in the install tree you can set the rpath by setting 
the INSTALL_RPATH target property on the executable.  Take a look at the 
documentation of SET_TARGET_PROPERTIES for details.
