Fix unused cache warning after multiple configure iterations 

The curses dialog (ccmake) allows variables to be specified on the
command line.  If any of these variables is used during any configure
iteration or during generate we must not warn about it.

The Qt dialog (cmake-gui) allows variables to be added and removed in
the GUI interactively.  If a variable is added, removed, and then added
again we must still warn if it is unused.
