I'm trying to build openCV on Raspberry Pi, following the instructions at https://www.pyimagesearch.com/2017/09/04/raspbian-stretch-install-opencv-3-python-on-your-raspberry-pi/ .
After installing all dependencies, I'm running:
cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D INSTALL_C_EXAMPLES=OFF \
-D INSTALL_PYTHON_EXAMPLES=ON \
-D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules \
-D BUILD_EXAMPLES=ON ..
Which gives me the following output on stdout:

Can anyone help me understand why this is failing? I'm pretty new to OpenCV and CMake, so not sure what I'm doing wrong, or how to fix it...
