Issue with Source Setup.sh

Hello all,

I'm trying to follow the instructions on the README though I've been running into some issues with setting the environment variables up with source setup.sh. From what I can tell, upon running setup.sh, it tries looking for a file called thisroot.sh which I don't seem to have anywhere on the computer after following the instructions of the README. I'm not sure where this file is supposed to come from or if I'm supposed to create it myself. It seems like one of the other Issues here on this gitlab page for Ph2_ACF mentions this problem as well though (#1 (closed)). However, even if I did modify my setup.sh file as suggested here, I would still be missing thisroot.sh so I'm somewhat confused as to how I should go about fixing this. Is thisroot.sh necessary or should I go about this a different way? For reference, I attached the output for the source setup.sh command below.

[root@hexpc8 Ph2_ACF]# source setup.sh
bash: /bin/thisroot.sh: No such file or directory
=== DONE ===
[root@hexpc8 Ph2_ACF]# 

Any help with this would be greatly appreciated.
