If all the dependencies are in the repo, why then does radiant not compile ?
i was referring to the game - i don't think we should put something as gtk into our repo. but the game should hopefully be compilable without the need to install external deps (and if not, we should fix that for sure)
gtkradiant is a totally different story. we could still collect everything that is needed in a github project - but as i said for this before, it must get maintained. And that is work that a windows user has to do in order to check whether updates works. So for gtkradiant I would really rather say a) set up on your own - free versions each time b) only compile the game. And in terms of contributors I think that people are more interested in helping out with the game than the editor (even though i might be wrong here)
It would also be possible to just switch the build system to something like cmake or premake. then we only have to maintain one build system and could generate project files for almost every ide out there. But to be honest, i'm not equipped with a lot of experience about cmake or premake. I would prefer cmake over premake - but even that is not based on wisdom - but ... feelings.
