    cmake- build chm file by default on Windows
    
    The chm targets were already enabled by default, but not built, that
    is one still had to explicitly add the 'chm' target toi make or ninja
    for chm files to get built.
    This turned out to be a problem for our Windows build scripts
    which are driven by jhbuild. While jhbuild allows to set ninjaargs
    to drive ninja, that parameter appears to ignore targets and will
    only accept command line options.
