So that's a fork of a ~10 years old fork of Qt. Copperspice originally forked, in part, because Qt was not close enough to the C++ standards, and now this (outdated) GUI library is being forked because they make use of a 4 years old C++ standard. Someone should fork LsCs to add support for mobile or new C++ standard. Looking forward to see this happen in 10 years (/s)
