That is the IBCM library for the IBCM CPC -- IB connection manager
It's not *necessary*; you could use the OOB CPC if you want to.
That being said, OMPI currently builds support for it (and links it
in) if it finds the right headers and library files. We don't
currently have configury to disable this behavior (and *not* build
RDMACM and/or IBCM support).
Do you have a problem / need to disable building support for IBCM?
