* norm - the library supports the norm:// protocol
* curve - the library supports the CURVE security mechanism
* gssapi - the library supports the GSSAPI security mechanism
* draft - the library is built with the draft api
When this method is provided, the zmq.h header file will define
ZMQ_HAS_CAPABILITIES.
RETURN VALUE
