LD_LIBRARY_PATH variable and Delphes library

I installed ROOT using conda on my new laptop, and I need to run a macro that uses the Delphes and ExRootAnalysis libraries. The last time I had this issue, someone else helped me (apparently by modifying the LD_LIBRARY_PATH variable), but now I need to do it independently. I’m almost clueless about paths and libraries so I would appreciate some guidance -and patience- at an elementary level. Thanks, and I apologize for the inconvenience!

ROOT Version: 6.26/02
Platform: macOSx64
Compiler: clang

May be this post can help: Load Delphes library to ROOT

Thanks a lot! I was actually able to follow the discussion there.
