title: janus gateway: configure shows websockets not enabled
body: <p>I am trying to use janus. First step, installation.
  I followed the instructions <a href="https://github.com/meetecho/janus-gateway" rel="nofollow noreferrer">here</a>. All is well. However, when I run</p>
  
  <pre><code>    configure prefix=/opt/janus
  </code></pre>
  
  <p>Relevant portions of the output are:</p>
  
  <pre><code>...
  checking for TRANSPORTS... yes
  checking for MHD... yes
  checking for lws_create_vhost in -lwebsockets... no
  checking for amqp_error_string2 in -lrabbitmq... no

  checking for PLUGINS... yes
  checking for SOFIA... yes
  checking for OPUS... yes
  checking for OGG... yes
  checking for EVENTS... yes
  checking that generated files are newer than configure... done

  <p>MY PROBLEM IS WITH THE ENTRY <strong>WebSockets:  no.</strong></p>
  
  <p>I checked in /usr/lib and here are the relevant files there:</p>
  
  <pre><code> /usr/lib/libwebsockets.a  /usr/lib/libwebsockets.so  
   /usr/lib/libwebsockets.so.11  /usr/lib/libwebsockets.so.5
  </code></pre>
  
  <p>And in /usr/include</p>
  
  <pre><code> /usr/include/libwebsockets.h
  </code></pre>
  
  <p>So, I think that libwebsockets is installed properly.  What needs to be done to get the webSockets transport enabled?</p>
  
  <p>I did look at <a href="https://stackoverflow.com/questions/24866712/implement-janus-gateway-for-webrtc">this</a> too. </p>
