  <p>I installed opencv with the following make options</p>
  
  <pre><code>cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON -D ENABLE_FAST_MATH=1 -D CUDA_FAST_MATH=1 -D WITH_CUBLAS=1 -D CUDA_NVCC_FLAGS="-D_FORCE_INLINES" ..

  <p>But after installing it I can't import cv2 within python3 of anaconda. I can however import cv2 from builtin python2 command. So I suppose it build for the python2 version as stated in the last line.</p>
  
  <p>How do I build for anaconda python3 ?</p>
