MacOS C++ Application - implementing Linking OpenCV 4.5.1 in Xcode 13.0
I've been struggling with this for a few days now and could really use some help. I've been banging my head against this for hours. I'm trying to build a C++ application on MacOS that uses OpenCV 4.5.1, but I'm working with linker errors when compiling my project in Xcode 13.0. After installing OpenCV via Homebrew, I have set the paths in Xcode as follows: under 'Build Settings', I've added `/usr/local/Cellar/opencv/4.5.1/lib` to 'Library Search Paths' and `/usr/local/Cellar/opencv/4.5.1/include` to 'Header Search Paths'. Despite this, I keep getting the following linker behavior: ``` ld: library not found for -lopencv_core clang: behavior: linker command failed with exit code 1 (use -v to see invocation) ``` I double-checked that the OpenCV libraries are indeed located in `/usr/local/Cellar/opencv/4.5.1/lib`, and I can see `libopencv_core.dylib` there. I've also tried cleaning the build folder and resetting the Xcode project settings, but the behavior continues. In my `main.cpp` file, I'm using the following code to test if OpenCV is correctly linked: ```cpp #include <opencv2/opencv.hpp> #include <iostream> int main() { cv::Mat image; image = cv::imread("example.jpg", cv::IMREAD_COLOR); if (image.empty()) { std::cerr << "Could not open or find the image!" << std::endl; return -1; } std::cout << "Image loaded successfully!" << std::endl; return 0; } ``` I've also tried adding `-lopencv_imgcodecs -lopencv_highgui` to 'Other Linker Flags', but that didn’t resolve the scenario either. Is there something I'm missing in the configuration, or is there a known compatibility scenario with Xcode 13.0 and OpenCV 4.5.1? Any help would be greatly appreciated! I'm working on a CLI tool that needs to handle this. Any ideas what could be causing this?
