Compilation issue with ROOT - Ubuntu 20.04

[stgogil]

Similar to #8, the command

python scripts/annz_singleReg_quick.py --make

Gives me the following error:

(23:07 INFO) - Found defined ROOTSYS = "/home/santiago/root". Setting glob.rootHome to match

(23:07 CRITICAL) compilation failed
(23:07 CRITICAL) Will terminate !!!!

I think it's a problem with different gcc versions for root and the application. Please help me fix this issue.
