To build GEANT4 11.2.0 in Ubuntu 22.04

Visuailization

I pick the Qt + openGL as the visualiization, for that we need

>sudo apt install qt6-base-dev libqt6charts6-dev qt6-3d-dev

the openGL should come with Ubuntu 22.04

Steps

>sudo apt install libexpat1-dev libxmu-dev linxkbcommon-dev
>cd Downloads
>wget https://gitlab.cern.ch/geant4/geant4/-/archive/v11.2.0/geant4-v11.2.0.tar.gz
>tar xzf geant4-v11.2.0.tar.gz
>mkdir geant4-v11.2.0_build
>cd geant4-v11.2.0_build
>cmake -DGEANT4_INSTALL_DATA=On -DCMAKE_INSTALL_PREFIX=/opt/geant4-v11.2.0 -DGEANT4_USE_OPENGL_X11=ON -DGEANT4_USE_QT=ON -DGEANT4_USE_QT_QT6=ON ../geant4-v11.2.0
>make -j10
