We typically write something like:

# file /must/ be in current dir (builddir) for proprietary tool:
__heap.o: lib/__dfl_heap.o
        cp -f $< $@

Make finds $(srcdir)/lib/__dfl_heap.o via VPATH, if any, and
sets `$<' accordingly
  (of course this won't work if in the above example the
  filenames (including path parts, if any) of data-in-source-tree
  and data-in-build-tree and exactly the same).

I case this is portable (is it?) I think it could be a touch better?

oki,
