title: zmq, zerorpc deployment on Heroku
body: <p>I am trying to deploy ZMQ on Heroku with Node.js</p>
  
  <p>I was able to compile ZMQ and get the libs inside my Node build,
  however I cannot figure out how to setup the Heroku Environment, specifically NPM ZMQ package to search the right folder to find the libzmq files.</p>
  
  <p>thus, stuck at ../binding.cc:28:17: warning: zmq.h: No such file or directory</p>
