[CMake] custom commands and dependence problems

[Bradley Lowekamp]

Hi Brad,

I do not under stand what property you are recommending me getting  
here. The purpose of this code it to try to add dependencies of source  
code to generated header file. Lets just say this is a greatly  
simplified version of what I am trying to do :)

Can source files depend on custom targets which don't generate files?

Also I have posted a response to my on post, when I tried to get this  
dependency working under the assumption that they can't.

Thanks
