Actually, you want either of these

set_target_properties(foo PROPERTIES INSTALL_NAME_DIR "@rpath")
or
set_target_properties(foo PROPERTIES MACOSX_RPATH 1)

There is no need to set it as a property on target x.

Yes, it'll work in 2.8.12 like this.

set_target_properties(x PROPERTIES INSTALL_RPATH "@loader_path/..")
