    Fix parsing of cache variables without a type
    
    These mainly come from the command line or manual entries in the
    CMakeCache.txt file. We want to stop at the first '=' because this is
    what is most likely to have been meant. The variable can be quoted if
    the '=' is intended.
    
    Caveat: What if one wants both '"' and '=' in a variable name?
