Ups, that definitely was a typo. Luckily,  I meant cmake-time.

Of course. The point is more that you can't see the feedback from E when 
running it at cmake time...

I also thought of that solution. I already started a hard fight with the 
regexps in order to grab the names of the generated sources from the (verbose) 
output of E. By splitting it to stdout AND stderr, i can also solve that 
problem quickly.

Thanks for the good idea and the quick reply!
