title: When build opencv, could not find the file "cv2.so"
body: <p>I compiled OpenCV 3.0.0 with <code>python2.7</code> in Debian system at a Board with a extended SD card (BeagleBone Black).</p>
  
  <p>After OpenCV installed, there seems no error. There are many generated files in the 'Lib' folder.</p>
  
  <p>Those files are named like:</p>
  
  <pre><code>libopencv_core.so
  libopencv_dataset.so
  libopencv_imgproc.so ...
  </code></pre>
  
  <p>I could not find the file <code>cv2.so</code>, even searched the whole file system.</p>
  
  <p>I have tried several times, just can not find <code>cv2.so</code>.</p>
  
  <p>Who knows the reason? Thanks.</p>
  
  <p><code>make</code> config checked, seems correct:</p>
  
  <pre><code>sudo cmake -D CMAKE_BUILD_TYPE=RELEASE \
  -D CMAKE_INSTALL_PREFIX=/usr/local -D
  </code></pre>
