The reason variables aren't getting set in lower directories is that the 
EXEC_PROGRAM command is not "inherited" into lower directories.  This 
unfortunately is a hold-over from a much earlier design of CMake and is 
now just a pain.  We have plans to solve this problem but it is not yet 
implemented.

Please create a feature request here:

Once it is created you can go back in and attach your prototype file. 
Then a developer will look at it.
