Great, thanks for that. Everything is back on schedule :)

I've pushed the use-generator-target topic to next. It does more porting to 
cmGeneratorTarget - enough to use it in GetIncludeDirectories. 

Hopefully it will stabilize quickly on the dashboard and I'll be able to get 
the include directories generator expressions in soon too.

Thanks,

Steve.
