title: How to use Boost Library with Emscripten
body: <p>I have a project need using websocket (or named pipe) in browser to communicate with native program.
  (Is it feasible by Webassembly?)</p>
  
  <p>I have wrote a c++ websocket with Boost Library and would like to compile it to wasm.</p>
  
  <p>But I have no idea how to use Boost Lib(not header only) with Emscripten.</p>
  
  <p>I try to bulid Boost Lib by this:

  <p>However, how should I link the lib when compiling project with Emscripten?</p>
  
  <p>Thanks!</p>
