Comment

// 1) Clone the OpenCV’s and OpenCV contrib repositories:

mkdir ~/opencv_build && cd ~/opencv_build
git clone https://github.com/opencv/opencv.git
git clone https://github.com/opencv/opencv_contrib.git

// 2) Once the download is complete, create a temporary build directory, and navigate to it:

cd ~/opencv_build/opencv
mkdir -p build && cd build

// 3) Install required Python's librabry for the build

pip install numpy

// 4) Set up the OpenCV build with CMake:

cmake -D CMAKE_BUILD_TYPE=RELEASE \
    -D CMAKE_INSTALL_PREFIX=/usr/local \
	-D INSTALL_PYTHON_EXAMPLES=OFF \
	-D INSTALL_C_EXAMPLES=OFF \
	-D WITH_TBB=ON \
	-D WITH_CUDA=OFF \
	-D WITH_V4L=OFF \
	-D WITH_QT=OFF \
	-D WITH_OPENGL=OFF \
	-D WITH_GSTREAMER=OFF \
	-D OPENCV_GENERATE_PKGCONFIG=ON \
	-D OPENCV_ENABLE_NONFREE=ON \
	-D INSTALL_CREATE_DISTRIB=ON \
	-D BUILD_opencv_world=OFF \
	-D BUILD_opencv_python2=OFF \
	-D BUILD_opencv_python3=ON \
	-D PYTHON3_INCLUDE_DIR=$(python3 -c "from distutils.sysconfig import get_python_inc; print(get_python_inc())") \
	-D PYTHON3_PACKAGES_PATH=$(python3 -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())") \
	-D OPENCV_EXTRA_MODULES_PATH=~/opencv_build/opencv_contrib/modules \
	-D PYTHON3_EXECUTABLE=$(which python3) \
	-D PYTHON_DEFAULT_EXECUTABLE=$(which python3) \
	-D BUILD_EXAMPLES=OFF ..

// 5) Start the compilation process:

make -j8

// 6) Install OpenCV with:

sudo make install

// 7) Creates the necessary links and cache to the most recent shared libraries

sudo ldconfig
