edit

Hello I am working on a opencv project on the rpi3 and I have this Cmakelist.txt file for it, now I want to add the WirringPi to the project so I could use DigitalWrite commands to the RPI3 What do i need to add to the cmake file?

This is the cmakelists.txt:

# cmake needs this line cmake_minimum_required(VERSION 2.8) # Define project name project(opencv_example_project) # Find OpenCV, you may need to set OpenCV_DIR variable # to the absolute path to the directory containing OpenCVConfig.cmake file # via the command line or GUI find_package(OpenCV REQUIRED) # If the package has been found, several variables will # be set, you can find the full list with descriptions # in the OpenCVConfig.cmake file. # Print some message showing some of them message(STATUS "OpenCV library status:") message(STATUS " version: ${OpenCV_VERSION}") message(STATUS " libraries: ${OpenCV_LIBS}") message(STATUS " include path: ${OpenCV_INCLUDE_DIRS}") if(CMAKE_VERSION VERSION_LESS "2.8.11") # Add OpenCV headers location to your include paths include_directories(${OpenCV_INCLUDE_DIRS}) endif() # Declare the executable target built from your sources add_executable(opencv_example example.cpp) # Link your application with OpenCV libraries target_link_libraries(opencv_example ${OpenCV_LIBS} )
