[CMake] Dependency checker

[Benjamin Schindler]

Hi

I've written a cmake script for the codesynthesis xsd compiler which
works kindof similar to the qt scripts calling moc etc.
The problem is, that I have no dependency checker. I'd need to parse the
xsd asked for and put all included xsd's in to the dependency list. And
this needs to be cross platform (so exec-program is not really an option...)

Is there a way in cmake to do that?

Thank you
