The goal here is to get rid of BRL-CAD's need for overriding commands
without necessarily solving all the problems in general so long as the
changes are independently useful and not specific to BRL-CAD's needs.
I think SOURCE_DIR and BINARY_DIR provide useful information, as will
the TARGETS global property discussed in another branch of this thread.

I would welcome this more complete solution too.
