Ah, ok, my bad.

I'm not worried about that part. Plain make seems to be able to deal with pidl
ok. It might be a bit more work in the makefiles, but this seems like the
easy part. One thing that'd help to convince people would be to show that
cmake generates s4 binaries that are way smaller than the ones generated by
the current build system. Simply stating that the new system isn't worse than
the old one doesn't really convince me, at least. :)

Right, but this is one of the killer features of the build system you're
proposing to replace. If you can't show that cmake supports these as well,
the next paragraph is pretty much a moot point.

Right, so that's the part I'd like to see in action. :)
