I compiled OpenCV 4.2 from source with the opencv_contrib and NONFREE algorithms, so to have the same configuration as me, follow these commands:
mkdir opencv_src && cd opencv_src
git clone https://github.com/opencv/opencv.git
git clone https://github.com/opencv/opencv_contrib.git
mkdir build && cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D OPENCV_GENERATE_PKGCONFIG=ON \
-D OPENCV_ENABLE_NONFREE=ON \
-D OPENCV_EXTRA_MODULES_PATH=~/opencv_src/opencv_contrib/modules ../opencv
# find out number of CPU cores in your machine
nproc # return 12 for me
make -j12
sudo make install
pkg-config --modversion opencv4
python3 -c "import cv2; print(cv2.__version__)"
