This fails spectacularly, because CZMQ uses compile-time decisions
about what version of ZMQ to support, and how. It's never been raised
as a necessary problem to solve. If it was, I'd start by detecting
this and asserting in zctx_new for instance. Second, perhaps by
switching to a runtime detection of the version.
