[Источник]
git clone https://github.com/opencv/opencv.git
git checkout -t origin/4.x

[Дополнительный репозиторий для сборки с Nvidia CUDA]
Путь до модулей этого репозитория нужно указать в параметре OPENCV_EXTRA_MODULES_PATH
git clone https://github.com/opencv/opencv_contrib
git checkout -t origin/4.x

[compiler]
sudo apt-get install build-essential

[required]
sudo apt-get install cmake git pkg-config

[optional]
sudo apt-get install libjpeg-dev libpng-dev libtiff-dev

[Для работы с WEB-камерой используем libv4l-dev вместо libdc1394-22-dev]
sudo apt-get install libv4l-dev

[Для сборки с системной библиотекой FFMPEG]
sudo apt-get install \
  libavcodec-dev libavformat-dev libavutil-dev libswscale-dev libavresample-dev \

[Дополнительный репозиторий для сборки с Nvidia CUDA (выполнить единоразово)]
git clone ssh://git@gitlab.tochka.ai:16822/nvidia/video-codec-sdk.git
Оригинальный репозиторий: git@gitlab.com:nvidia/video/video-codec-sdk.git
Скопировать все заголовочные файлы из директории ./video-codec-sdk/Video_Codec_SDK_12.2.72/Interface
в директорию /usr/local/cuda/include/

cd ~/opencv
git clean -dfx && mkdir -p build && cd build

[Примечание для сборки с GPU]
Не забывать обновлять репозиторий opencv_contrib до актуального состояния!
