title: cl' is not recognized as an internal or external command command nginx-rtmp
body: <p>I'm installing nginx with rtmp module, using msys and Visual Studio. </p>
  
  <p>When I run <code>nmake -f objs\makefile</code> it goes perfectly until I get this error:</p>
  
  <blockquote>
    <p>cl' is not recognized as an internal or external command command</p>
  </blockquote>
  
  <p>I'm using the instructions on <a href="http://www.helping-squad.com/nginx-rtmp-compile-for-windows/" rel="nofollow">this link</a> for the step by step configuration, using Windows 7 Professional.</p>
  
  <p>How can I fix this error?</p>
