title: import cv2 error, libcudart.so.6.5 no such file
body: <p>When invoked in python, cv2 is looking for the wrong libcudart.so. Here is the error after import cv2</p>
  
  <pre><code>ImportError: libcudart.so.6.5: cannot open shared object file: No such file or directory.
  </code></pre>
  
  <p>I have both CUDA 6.5 and 7.5 installed on my system. But other apps seem to have no problem finding 7.5.</p>
  
  <p>Here is my settings : ubuntu 14.04, OpenCV 3.0.0, python 2.7, cuda 6.5 and cuda 7.5 </p>
  
  <p>The LD_LIBRARY_PATH looks like</p>
  
  <pre><code>/usr/local/cuda/lib64:/usr/local/lib:/home/rspace/shogun-4.0.0/build-release/src/shogun:/usr/lib:/usr/lib/x86_64-linux-gnu
  </code></pre>
  
  <p>NOTE: the /usr/local/cuda is actually a link to /usr/local/cuda-7.5.</p>
