As I said in parallel to your response I'd prefer that distros
use a hammer like CMAKE_SKIP_INSTALL_RPATH so they do not have
to depend on the project supporting it with code like the above.
I'd like to discourage them from using CMAKE_SKIP_RPATH because
it is a pain for testing.

Of course your approach doesn't depend on any new CMake changes
so you can use it right now to get started.
