Thanks for your comments!
Working with others will certainly speed up things.

I also got pointed to this PPA repo here:
https://github.com/thopiekar/Cura-packaging
It probably needs some tweaking, but the dependency lists are much more refined 
than mine. May be a better starting point.

No, I haven't. I'm not 100% sure what to look for, but I'll check.

Good point. As far as I can tell, all sources are covered under AGPL3+.
cura_app.py says:
# Cura is released under the terms of the AGPLv3 or higher.
Uranium is missing a LICENSE file, but the source code files carry this line 
too. I haven't checked all of them, though.

Interesting, I didn't know this works.
This is exactly what thopiekar did in his PPA.

Ah, of course.

I'll check if/how this is possible. Building out-of-tree will probably be 
easier, though.
Is there a cmake/dh flag to do this. I searched, but haven't found anything 
suitable...

After reading thopiekar's package files, I think there may be some dependency 
problems. I'll look into this.

Very good, how do I sign up? :)
