Cannot use zmq-shared on windows

[ClosetGeek-Git]

I'm aware that there are pre-built binaries. In my situation I need to be able to link to libzmq as a shared library. If I modify binding.gyp to point it properly to zmq.h, zmq_util.h, and libzmq.lib and it still failed. It should be fixed or documentation should be clear that zeromq.js is only supported on windows as a static build via dynamically downloaded source files.
