after build opencv with -DBUILD_SHARED_LIBS=OFF, I still need external libraries to run apps with opencv.

I use a ubuntu 1604 python 3.6 docker image to set up the build environments. And successfully built opencv python3 with -DBUILD_SHARED_LIBS=OFF.

But when I copy the cv2.cpython-36m-x86_64-linux-gnu.so file to other container base on a same image, I still need to set up environments to use this library such as libjpeg, libpng, libwebp and so on.

How can I get the same result with the case directly use "pip install opencv-python"? When I use pip install opencv-python, I don't need to set up others environments any more.

try cmake -DBUILD_JPEG=ON -DBUILD_PNG=ON , etc, so it's using the provided 3rdparty codecs (from src), instead of trying to use your system's dynamic libs at runtime.

Hi, berak I still have a little problem here. I have added all the -DBUILD_xxx parameters which seem related ON now, but ImportError:libdc1394.so.22 come out all the time. I can't figure out, can you give me some advice here? Thanks~
