How to compile a SubProcess directory in aMC@NLO

You need to set the following flag:

1. export madloop=True
2. export fastjet_config=None # if you use fjcore otherwise put the path to fasjet-config file
3. unset lhapdf # if you didn't link to lhapdf otherwise the path to lhapdf-config

If it didn't work this is likely that the Source directory was not compile with the same flag. So you need to recompile it with the same flags.
