Its that simple? :-) I'll try it soon as i get to work. I forgot to mention 
one more thing. Id like to know even update the 'INCLUDE_DIRECTORIES()'.

Maybe ill set a cached variable, update it with the full path names of the 
directories to include and then update that in the parent CMakeLists.txt 
with INCLUDE_DIRECTORIES(${ARCH_INCLUDE_DIRS}).

Thanks!
