title: How to correctly include/install libpng?
body: <p>I'm trying to use <a href="http://www.libpng.org/pub/png/libpng.html" rel="nofollow">libpng</a> into my project. I've installed it, by downloading the setup of the <strong>Complete package, except sources</strong> from <a href="http://gnuwin32.sourceforge.net/packages/libpng.htm" rel="nofollow">here</a> and executing that <code>.exe</code> installation file.</p>
  
  <p>But when I include it using </p>
  
  <pre><code>#include &lt;png.h&gt;
  </code></pre>
  
  <p>or</p>
  
  <pre><code>#pragma comment(lib, "png.h")
  </code></pre>
  
  <p>this wouldn't work. How do I please to correctly install it to be able to include it?</p>
