현재 설치된 opencv 버전 확인

$ pkg-config --modversion opencv

아래와 같이 나와야 된다.

소스코드와 contrib 파일 가져오기

opencv 디렉토리를 만들고 wget 명령으로 소스 파일을 다운로드한 다음 압축을 해제한다.

$ mkdir opencv
$ cd opencv
$ wget -O opencv-3.4.11.zip [<https://github.com/opencv/opencv/archive/3.4.11.zip>](<https://github.com/opencv/opencv/archive/3.4.0.zip>)
$ wget -O opencv_contrib-3.4.11.zip <https://github.com/opencv/opencv_contrib/archive/3.4.11.zip>
$ unzip opencv-3.4.11.zip
$ unzip opencv_contrib-3.4.11.zip

opencv-3.4.11 디렉토리로 이동 후 build 디렉토리를 만든다.

$ cd opencv-3.4.11/
$ mkdir build
$ cd build

cmake 수행

설치된 CUDA 버전에 따라 CUDA_TOOLKIT_ROOT_DIR 경로를 수정한다.

opencv 3. 버전인 경우 CUDA 12이후 버전에서 지원하지 않음 (아래 링크 참조)
