[CMake] custom command question

[Doug Henry]

No, since it is a dependency of a source file that is included in the
executable I would expect it to be handled (it was in previous releases).
It seems that cmake does know about it, because it gives an error with the
correct path to the file that needs to be generated.  I don't know why cmake
will not run the custom command anymore.  I suspect that the source files I
generate this way are created because they are in the list as you suggest.
