2. Clone OpenCV

git clone https://github.com/opencv
git clone https://github.com/opencv_contrib

git checkout tags/4.5.5 -b 4.5.5v
git checkout tags/4.5.5 -b 4.5.5v

We'll install OpenCV 4.5.5v. If you want to install another, try to find the release and tags in the official git.

3. Build OpenCV

cd opencv
mkdir build
cd build
