I've added opencv as follows Download it and build it git clone https://github.com/opencv/opencv cd opencv mkdir build && cd build cmake -DBUILD_SHARED_LIBS=OFF -DCMAKE_INSTALL_PREFIX=../install .. sudo make -j$(sysctl -n hw.logicalcpu) sudo make install Go to install Copy all .a files from lib and lib/opencv4/3rdparty/ into your project. I.e. MyProject/Libraries/ Get to install/include/opencv4/ and copy the opencv2 folder into your project. Go to your project settings Targets -> Search Paths -> Header Search Paths Add the following path $(PROJECT_DIR)/Path/to/opencv2/ NOTE: I currently have a problem with my Xcode and I guess it's related to opencv, so you may also encounter this issue.
