I'm just implementing the warnings....
There is a problem with the new keywords.

If I make the warning "... use the CONFIG_MODE keyword ..." and the developer 
does this then, then his project will not work anymore with older cmake 
versions, because they don't know CONFIG_MODE.

If the warning says instead "... use the NO_MODULE keyword ..." then the 
project will still work with old and new cmake versions correctly.

I think the nicer MODULE_MODE and CONFIG_MODE keywords are not worth breaking 
backward compatibility of users projects (not cmake) this way.
