1.  The only way to do this would be to put each library in a separate 
SUBDIR directory.

The SET command will work, but your cache will still not have the value.
You can use a SET(CACHE FORCE) to change the cache.

MESSAGE is not treated as an error.  ccmake currently reports it as an error
but does not treat it like an error.   SEND_ERROR causes ccmake and CMakeSetup
to not go on to the generate stage.
