DragonX256  filed a orphan request for qtox-git :
PKGBUILD needs to be updated.
I write a letter to email of current maintainer and it didn't answer.
- Need using of upstream repo (qTox/qTox, not tux3/qTox)
- Migrate to a CMake-based build (It's new build type, which will
fully replace QMake in future)
I already have a new PKGBUILD, which is fixes these "bugs".
