SETUP AT SLAC

export ATLAS_LOCAL_ROOT_BASE=/cvmfs/atlas.cern.ch/repo/ATLASLocalRootBase
source ${ATLAS_LOCAL_ROOT_BASE}/user/atlasLocalSetup.sh
lsetup "root 6.20.06-x86_64-centos7-gcc8-opt"

Note that the Makefile in this fork is slightly different from the original repo:

tpcosmics is not compiling with the setup above, so I removed it from the makefile (hopefully we won't need it). For some reason VectorDict_rdict.pcm was not being found, so I added a cp statement to the VectorDict makefile rule.
