Hi Alexis,
thanks a lot for your extremely helpful explanation.

Makes sense.

Makes sense. I was not up to this issue - just was dealing with errors
step by step but I guess this would have been my next question. ;-)
Thanks a lot for the proactive answer.

OK, I need to deal with this.

I'll check upstream Git or file an issue about this.
Unfortunately your patch did not applied cleanly - no idea why. I have
added it manually and reread your explanation which I think are
implemented correctly. Unfortunately in my pbuilder I get the same
cmake failure as before and since I think I've now understand the issue
I'm even more in vain since its not working anyway for me but you
confirmed that it should work. Could you be so kind to have another
look on the latest state in Git?
Thanks again
Andreas.
