I want to install HepMC3 following this gitlab page
In point number 4 it says: In order to build with ROOTIO put the following flags and define LD_LIBRARY_PATH:
how can I know the ‘path_to_ROOT6_installation’ and ‘path_to_ROOT6_libraries’ ? I did my installation using Alibuild as I do analysis in the ALICE collaboration.
_ROOT Version:ROOT 6.20/08
Thanks for your help,
