after compiling and installing opencv3.2's module cv2.so for python3.6m, import cv2 leads to undefined symbol

Question

I have been compiling and installing OpenCV 3.2.0 for python 3.6m on my Ubuntu 16.10 workstation.

Unfortunately, I get the following error:

user@host ~/D/o/cmake> python3 -c "import cv2"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: /usr/local/lib/python3.6/dist-packages/cv2.cpython-36m-x86_64-linux-gnu.so: 
    undefined symbol: _Z13pyopencv_fromIN2cv4MatxIdLi4ELi4EEEEP7_objectRKT_

I have been configuring cmake as follows:

cmake \                                                                                   
    -D BUILD_opencv_python3=ON \                                                          
    -D HAVE_opencv_python3=ON \                                                           
    -D PYTHON3LIBS_VERSION_STRING=3.6m \

    -D CMAKE_INSTALL_PREFIX=/usr/local \                                                  
    -D BUILD_NEW_PYTHON_SUPPORT=ON \                                                      
    -D INSTALL_C_EXAMPLES=ON \                                                            
    -D INSTALL_PYTHON_EXAMPLES=ON \                                                       
    -D BUILD_EXAMPLES=ON \                                                                
    -DENABLE_PRECOMPILED_HEADERS=OFF \                                                    
    -D OPENCV_EXTRA_MODULES_PATH=/home/user/Downloads/opencv_contrib/modules ..      

Any idea on what might have caused the undefined symbol? Might be this related with ldconfig?
