You haven't fully defined when you want (and don't want) these targets
to be run, so I can't be sure, but it sounds like you might want to use
order-only prerequisites:

        copy_object: | object

See the GNU make manual.

Another option is to use $(filter ...) with the MAKECMDGOALS variable,
something like:

        copy_object: $(filter object,$(MAKECMDGOALS))
