There's no way to do this right now as a user.  Well, you could do it
by duplicating a lot of the automake Makefile machinery.  That is
likely to be a big pain though.

Won't foo.cc and foo.hh depend on bar.idl, not bar.cc?  I thought the
IDL compiler would read the .idl files and not the .cc files.

Direct IDL support would probably be a useful addition to automake.
There have been discussions of this in the past, and some patches
(which I admit I haven't read).  I don't think this will go in 1.5,
but it would probably be appropriate for the next major release.  I'm
guessing it will be somewhat of a pain due to the wide variance
between IDL compilers.
