Only the letters up to the first underscore are used for the grouping in cmake-gui. For larger hierarchical projects, this grouping feature is pretty important if you want any chance of keeping the variables manageable in the GUI. The project-specific prefix is also good protection against name clashes with other parts of the build (always consider the possibility that your project may one day be used as part of some larger parent project, pulled in by add_subdirectory()). -- Craig Scott Melbourne, Australia https://crascit.com
