I'm on debian 10 and that didn't work, but I suspect it's something to do with my current installation that complains about a missing Qt4 software even after installing that (That I'll research when I have the time).
sudo docker run -it debian:10 apt update apt install qtbase5-dev build-essential g++-8 qt5-qmake qt5-default git git clone --recursive -j16 https://github.com/francescmm/GitQlient mkdir build && cd build qmake ../GitQlient && make -j16
