I should add: this doesn't work (at least, not nicely and without 
fiddling with PARENT_SCOPE), since I need to change another 
(function-local) variable based on the value of ${bar}.

After thinking about it a bit more, this bit of autotools-inspired 
hackery seems to suffice: 'if("!${bar}" MATCHES "!CFLAGS")'. Except I 
think I found another bug (stay tuned) :-).
