title: 'cp' is not recognized as an internal or external command
body: <p>I tried to run a project using custom build in FlashDevelop:</p>
  
  <pre><code>$(CompilerPath)\haxe.exe $(ProjectDir)\compile-js.hxml
  </code></pre>
  
  <p>, but I get this error:</p>
  
  <p>'cp' is not recognized as an internal or external command,</p>
  
  <p>here is the compile-js.hxml file, is there any idea how to solve this?</p>
  
  <p>compile-js.hxml</p>
  
  <pre><code>#sources
  -main Cocktail
  -cp ../../src/
  -cp src
  
  #binary
  -js bin/js/Main.js
  --macro Cocktail.create('src/index.html','Main')
  
  #copy assets directory
