title: OpenCV installation stuck at [ 99%] Built target opencv_perf_stitching with no error
body: <p>So I am installing the latest version of OpenCV 3.2.0 and it just got stuck on 99% (even though I passed nproc to -j for make it took really long time and my nproc output is 24) and I wonder if there's a solution as I prefer not to stop it. I am not receiving any error:</p>
  
  <pre><code>CUDA 8
  Python 3.4.3
  OpenCV3.2.0
  Ubuntu 14.04
