You shouldn't do this to get the list of source files.
If you list the files in the cmake file, then cmake will notice if a file has 
been added or removed and rerun.
If you are using GLOB, the cmake files are not modified and so cmake doesn't 
rerun if some file has been added or removed, this is especially inconvenient 
if you update your sources from a version control system where you don't 
know/care whether some file somewhere has been added or removed.
