    CMake - update installation components
    
    Installation is normally only done in preparation of packaging the docs.
    At that point one would want to install all documents in a given format
    at once. So make the installation components document name independent.
    There are now two components: ghelp and chm. One for integration on linux
    into the gnome help system and one for integration on Windows.
    All other document types don't define installation targets so no other
    components for installation are defined either.
