Initializing the Dependencies

Before continuing with the build, the necessary setup scripts for ROOT and Geant4 (unless a build without Geant4 modules is attempted) should be executed. In a Bash terminal on a private Linux machine this means executing the following two commands from their respective installation directories (replacing <root_install_dir> with the local ROOT installation directory and likewise for Geant4):

source <root_install_dir>/bin/thisroot.sh
source <geant4_install_dir>/bin/geant4.sh

On the CERN LXPLUS service, a standard initialization script is available to load all dependencies from the CVMFS infrastructure. This script should be executed as follows (from the main repository directory):

source etc/scripts/setup_lxplus.sh
