[Halld-offline] compiling GlueX software in ubuntu 22.04

[Beni Zihlmann]

Hi All,

I managed to run our installation scripts almost to the end compiling 
and linking
the GlueX software in Ubuntu 22.04.
The last hurdle to take is linking hdgrean4 where it fails due to 
messages like this
.....
undefined reference to `TCrossSection::PairProduction(TPhoton const&, 
TLepton const&, TLepton const&)'
undefined reference to `TCrossSection::TripletProduction(TPhoton const&, 
TLepton const&, TLepton const&, TLepton const&, TLepton const&)'

anyone knows in which library these methods are supposed to be in?


cheers,
Beni
