### Set up RPATH for RDC to simplify finding RDC libraries. Please note that
### ROCm has a setup_env.sh script which already populates these variables.
### These variables are then used inside compute_utils.sh.
###
### We need to append additional paths to these variables BEFORE sourcing
### compute_utils.sh
