获取opencv mingw 编译后文件，网上很多教程

cmakelist.txt配置

cmake_minimum_required(VERSION 3.10)
project(Rasterizer)

set(OpenCV_DIR E:\\platform\\opencv4.10.0build\\install\\x64\\mingw\\lib)

set(CMAKE_CXX_STANDARD 26)
find_package(OpenCV REQUIRED core)

include_directories(E:\\platform\\eigen3.4\\include\\eigen3
                    ${OpenCV_INCLUDE_DIRS})

set(DLL_PATH "E:/platform/opencv4.10.0build/install/x64/mingw/bin")

file(GLOB DLL_FILES "${DLL_PATH}/*.dll")

add_executable(Rasterizer main.cpp rasterizer.hpp rasterizer.cpp Triangle.hpp Triangle.cpp)

foreach(DLL ${DLL_FILES})
    add_custom_command(TARGET Rasterizer POST_BUILD
            COMMAND ${CMAKE_COMMAND} -E copy_if_different
            "${DLL}"
            $<TARGET_FILE_DIR:Rasterizer>
    )
endforeach()

target_link_libraries(Rasterizer #[[${OpenCV_LIBS}]] ${DLL_FILES})

这里解释一下为什么要自己添加dll文件：

因为在OpenCVConfig.cmake文件中

This file will define the following variables:

# - OpenCV_LIBS : The list of all imported targets for OpenCV modules.

但是它没有指明OpenCV_LIBS有什么文件,所以需要自己手动添加链接库
