Hi Gregor,

The intention of my refactoring effort was to make generate-time classes 
like cmGeneratorTarget not depend on configure-time classes like cmTarget 
and cmMakefile at all. The cmMakefile class at least is tightly integrated 
to the current cmake language. I've made some effort to remove some of the 
other non-language related responsibilities it has, but there is more to do. 
I've also put work into to making cmGeneratorTarget not depend on cmTarget, 
but there is more to do there too.

Isolating the different classes would be a step along the way to introducing 
a new cmake language. It would also make better cross-compiling features 
possible such as multi-configuration builds (host+target etc).

I think such a thing would be out of date quite quickly, but the best 
guideline I can give is to try to separate the code which is dependent on 
cmMakefile+cmTarget from the code dependent on generators+cmGeneratorTarget.

Do you have a more-specific query?

Thanks,

Steve.
