This assumes that the processor is the bottleneck; which it is not.
IO is. Which Coolo also stated in his email on this thread.
Simply doing a stat on all CMake*txt files already takes an enormous 
amount of time on a big tree[1] (that doesn't fit fully in cache) and 
should never be done whatever I do in a subproject. The only exception is 
if I alter the CMake*txt file in that subdir or subdirs under it.
In other words; honor the hierarchic tree that project define and maintain 
for a good reason; to speed up development by separating out concerns.
