title: FFMPEG build error
body: <p>I've been trying to build a LGPL copy of ffmpeg and I have tried various different configure methods. I downloaded the latest source from the ffmpeg site and used the following simple configure </p>
  
  <pre><code>./configure --enable-memalign-hack --enable-pthreads --enable-shared --disable-static
  </code></pre>
  
  <p>However every time I try to build it I only end up with "avdevice-53.dll" and the error message like this </p>
  
  <pre><code>install: cannot stat 'libavdevice/avdevice.lib' : No such file or directory
  make: *** [install-libavdevice-shared] Error 1
  </code></pre>
  
  <p>What am I doing wrong?</p>
