Hi David,
That's certainly interesting. I've stuck in those you suggested, and
a few more (not exhaustively at this stage), but the list of errors
doesn't seem appreciably shorter. Is there a general rule about the
order of the libraries? You're probably going to tell me this can be
deduced from the VTKLibraryDepends.cmake file. :-]
Cheers
Gib
