In my experience, if make is called recursively correctly with "$(MAKE)" rather than with a new non-parallell invocation of "make" this is a non-problem as all parallell jobs will be put in the recursive call of make which needs it.

If you prefer to do it that way, you can have your top Makefile include all sub.mk files in the directory structure that it is able to find. regards Henrik
