Successfully built opencv 3.3.0 but no cv2.so found [closed]

edit

under ubuntu 14.04.

The cmake commands are: cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_CUDA=ON -D ENABLE_FAST_MATH=1 -D CUDA_FAST_MATH=1 -D WITH_CUBLAS=1 -D INSTALL_PYTHON_EXAMPLES=ON -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-3.3.0/modules -D BUILD_EXAMPLES=ON ..

After make and make install, there are no cv2.so in neither /usr/local/lib/python2.7/site-packages/ nor the build directory. I checked the build folder of opencv 3.0 previously used, there's cv2.so.

Does anyone know how to solve this? thanks! The cmake output is:
