Why do you do this ?

-      set(CMAKE_INSTALL_RPATH_USE_LINK_PATH TRUE)
+      set(CMAKE_INSTALL_RPATH_USE_LINK_PATH FALSE)

Then you have to manually collect all RPATHs you need (e.g. if some libs were 
in /opt/ or /home/foo/lib/ or ... ) , the only RPATH will be the one from 
CMAKE_INSTALL_RPATH.
