[CMake] map structure on cmake script

That's fine if ${KEY} doesn't have spaces nor characters that aren't 
allowed in variable names. As I'm using a string containing compiler 
flags and stuff, this solution isn't possible. A workaround would be 
computing a hash from the string and using it as a key, but once again, 
it'd be a pain in the *** to do it in cmake script.
