To help us debug your issue please explain:

The fix from issue #575 doesn't help as OpenHPC removes the static lib and installs to /opt/ohpc/pub/libs/gnu8/openmpi3/opencoarrays/2.6.3/

What you were trying to do (and why)

caf --version

What happened (include command output, screenshots, logs, etc.)
