22 #  Description:
23 #    Several functions that help organising the source tree.
24 #    [ADD/SET]_SOURCE_FILES - Writes source files to the cache by force and
25 #                             adds the current directory.
26 #                             Also compiles multiple source files into a single
27 #                             one by including them
28 #                             Use COMPILATION_[BEGIN|END] in
29 #                             [ADD|SET]_SOURCE_FILES and specify the name of
30 #                             the new source file after COMPILATION_BEGIN
31 #    GET_ALL_HEADER_FILES   - Finds all header files recursively.
32 #    GENERATE_SOURCE_GROUPS - Set Visual Studio source groups.
