Clean up cmake files (Part 2)

Browse Source 
I've kept just one cmake project, in the root directory. The
subdirectories just set up the targets.

The asm compiler is serached just one time, from the root
directory cmake file.

Global compilation flags are set in the root cmake file, and
each subdirectory cmake file sets specific flags if necessary
(e.g., programs need the -u_start specified)
