title: WebAssembly include OpenCV
body: <p>I have C++ code that manipulates images with OpenCV and I'd like to compile it with <code>emscripten</code>. But <code>emscripten</code> doesn't find OpenCV if i type:</p>
  
  <pre><code>em++ test.c -s WASM=1 -O3 -o test.js -lopencv_highgu
  </code></pre>
  
  <p>The warning i get:</p>
  
  <pre><code>WARNING:root:emcc: cannot find library "opencv_highgui"
  </code></pre>
  
  <p>I guess <code>emscripten</code> doesn't use my normal include path. So the question is how can i compile my C++/OpenCV program to WebAssembly</p>
