# OpenCV_LIBS

prebuilt OpenCV libraries for convenient usage.

## 预编译的 OpenCV 库

* `opencv-4.12.0-withContrib-mingw64-windows`：opencv-4.12.0 版本，带 opencv-contrib，模块化编译为多个库（每个模块分开编译）
* `opencv-4.12.0-withContrib-worldOn-mingw64-windows`：opencv-4.12.0 版本，带 opencv-contrib，编译为单个 libopencv_world4120.dll 库



## 用法
（1）添加系统环境变量

下载`opencv-4.12.0-withContrib-worldOn-mingw64-windows` 到本地，将`D:\opencv-4.12.0-withContrib-worldOn-mingw64-windows\x64\mingw\bin`）添加到系统环境变量中

（2）示例程序

```cpp
#include <iostream>
#include <opencv2/opencv.hpp>

int main(int argc, char **argv) {
    cv::Mat img = cv::Mat::zeros(cv::Size(640, 480), CV_8UC3);
    cv::imshow("image", img);
    cv::waitKey(-1);

    return 0;
}
```

（3）编写 CMakeLists.txt（可以用于 Release 或 Debug 模式）

```cmake
cmake_minimum_required(VERSION 3.16)
project(test_opencv)

set(OpenCV_DIR "D:/opencv-4.12.0-withContrib-worldOn-mingw64-windows")
find_package(OpenCV REQUIRED)
MESSAGE(STATUS "OpenCV_Version: ${OpenCV_VERSION}")
MESSAGE(STATUS "OpenCV_Include_DIRS: ${OpenCV_INCLUDE_DIRS}")

add_executable(test_opencv test_opencv.cpp)
target_link_libraries(test_opencv ${OpenCV_LIBS})
```
