Search in the manual for VPATH. Hopefully my other reply has enough hints to
solve some of your issues.

Using your post as a jumping off point...

Has anyone a hint to a half-decent makefile link/faq for (gmake) newbies?
It's understandable that such gets asked here. Would be nice to have a
somewhere to point at. The gmake manual is very comprehensive and
invaluable but unfortunately incomprehensible until just a few basics have
been grasped.
