E. G. Patrick Bos 9fbfa40bab Problem: when linking to libzmq in my project, I want zmq symbols to remain invisible to users of my library. There is no way to control this, since visibility is set automatically through ZMQ_EXPORT based on OS and compiler. ...

Solution: add a preprocessor variable ZMQ_NO_EXPORT that, when set, bypasses the automatic ZMQ_EXPORT determination block and just sets ZMQ_EXPORT to empty.

By combining this solution at configuration time with manually passing -fvisibility=hidden to CXXFLAGS, I solved my visibility problem. Just passing -fvisibility=hidden is not enough, because __attribute__ ((visibility ("default"))) has higher priority.
