- name: Install opencv

with:
opencv_tag: '4.6.0' # Optional. Default is '4.6.0'. An env var 'opencv_tag' will be defined.
BUILD_LIST: 'core,imgcodecs,imgproc' # Optional. Default is 'core,imgcodecs,imgproc'. The opencv modules(libraries, components) to be build, separated with `,` and no spaces.
BUILD_SHARED_LIBS: 'OFF' # Optional. Default is 'OFF'. Build shared opencv librarires, should be "ON" or "OFF".
BUILD_WITH_STATIC_CRT: 'OFF' # Optional. Default is 'OFF'. Build with static C Runtime Library?(only when MSVC), should be "ON" or "OFF"To set the correct paths, you could add to your CMakeLists.txt:
set(OpenCV_STATIC ON) # This is required when on Windows using static build of OpenCV. If not set, will give hint "not compatible"
