Debian builds with libibverbs because it is available -- we'd be doing
a disservice to those who have the hardware if we didn't.

Because we build with it, Open MPI packages depend on it. So if you
install Open MPI on Debian (and hence Ubuntu and ....), you get libibverbs.

So yes, suppressing the warning would be great as a default.

And generally speaking, we prefer to not diverge from upstream so if
you made it a default, we wouldn;t have to differ in what we
ship. That's how the thread started.

Thanks to all for considering this.
