 * cmSourceGroup holds a regular expression and a list of files.  When
 * local generators are about to generate the rules for a target's
 * files, the set of source groups is consulted to group files
 * together.  A file is placed into the last source group that lists
 * the file by name.  If no group lists the file, it is placed into
 * the last group whose regex matches it.
