It's helpful if you describe in words what you want to do.

If you're trying to fail immediately if a directory doesn't exist, you
can do something like this:

  $(if $(wildcard $(FINALDESTDIR)/.),,$(error $(FINALDESTDIR) does not exist))

This also uses only make constructs so is slightly more portable.
