[CMake] custom commands and dependence problems

[Bradley Lowekamp]

That looks like some good documentation there. Quite useful. However,  
as I was saying my build is a bit more complicated. I uses to do things  
quite similar to that. I can't any more. So I have tried to changes  
things a little bit to get it working. The additional complication is  
that at this point of the cmake code I don't know all the cpp files  
that will depend on the generated header files. So I am trying to make  
a general target that the other source files can depend on when I know  
what the source files are. I have tried a couple of solutions. And both  
of the changes didn't work. When I then simplified things, to a bit of  
CMake code that did not work the way I expected, I have posted that  
code. I would like to know if this code SHOULD work, or what am I not  
understanding about cmake.

This is the other post related to this problem:

Thanks
