Can you generate it at cmake time instead of build time?  ParaView has 
an example of this.
qt4_add_resources does a poor man's dependency scanning and the file 
needs to exist.

cmake experts/developers:  can an add_custom_command take a regex or 
something to do custom depenency scanning on a file in a non-C format?
Or is there some way to hook in another generated C format file that 
that can act as a proxy?
