I thought it was a typo in your code and that the wrong extension was 
being used inside the FOREACH.  It is perfectly valid to set source file 
properties for sources that are never actually included in targets 
(because the command doesn't know if the source is used in a target that 
is added after the command), so no error is given for a typo like this.

If it is not a typo please try unrolling the loop for a couple of the .c 
tests and make sure it works outside the FOREACH.
