OpenCV MingW配置

项目场景：

OpenCV VScode MingW配置

问题描述

使用MingW编译时出现bug：

[build] C:/opencvild/include/opencv2/core/utility.hpp:719:14: error: 'recursive_mutex' in namespace 'std' does not name a type
[build]  typedef std::recursive_mutex Mutex;
[build]               ^~~~~~~~~~~~~~~
[build] C:/opencvild/include/opencv2/core/utility.hpp:719:9: note: 'std::recursive_mutex' is defined in header '<mutex>'; did you forget to '#include <mutex>'?
[build] C:/opencvild/include/opencv2/core/utility.hpp:61:1:

---

原因分析：

从官网下载的OpenCV 库是支持MSVS 编译的
使用Visual Sudto Communiny 2022 Rlae x86 amd64编译没问题，其为Visual Studio 2022环境包，
但是不支持mingw64

---

解决方案：

需要进行make编译为支持mingw64的，或者直接下载编译好的OpenCV
下面附上链接：
https://github.com/huihut/OpenCV-MinGW-Build/tree/OpenCV-4.5.5-x64/x64/mingw/lib

随后更改CMakeLists.txt，进行库链接
附上代码

cmake_minimum_required(VERSION 3.10)

project(test1vb)

# 指定 OpenCV 的根目录（使用 MinGW 编译的 OpenCV）
set(OpenCV_DIR "D:\\opencv\\x64\\mingw\\lib")

# 查找 OpenCV
find_package(OpenCV REQUIRED)
if(NOT OpenCV_FOUND)
    message(FATAL_ERROR "OpenCV not found!")
endif()

# 添加头文件路径
include_directories(${
    
    OpenCV_INCLUDE_DIRS})
# include_directories("${PYLON_DIR}/include")

# 创建可执行文件
add_executable(${
    
    PROJECT_NAME} src/Main.cpp)

# 链接 OpenCV 库
target_link_libraries(${
    
    PROJECT_NAME} ${
    
    OpenCV_LIBS})
