Win10+VSCode搭建opencv+C++环境（2）

Win10+VSCode搭建opencv+C++环境（1）

前面都OK之后，还要记得添加opencv的环境变量，不然的话，后面会提示找不到libopencv_highgui348.dll等一系列dll文件

其中MinGW是我们自己新建的空文件夹，用来存放opencv经过cmake编译后的文件，D:\opencv\build\x64\MinGW\bin文件夹下存放的就是.dll文件

好，现在为止所有环境都搞定了，写个cpp试一下

#include<opencv2/opencv.hpp>
#include<opencv2/highgui.hpp>
using namespace cv;
int main()
{Mat img=imread("D:/lzb-soft-dir/vs-code/test.jpg");cv::imshow("image",img);cv::waitKey();return 0;
}

还要配置一下这三个文件

launch.json

{// Use IntelliSense to learn about possible attributes.// Hover to view descriptions of existing attributes.// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387"version": "0.2.0","configurations": [{"name": "g++.exe - 生成和调试活动文件","type": "cppdbg","request": "launch","program": "${fileDirname}\\${fileBasenameNoExtension}.exe","args": [],"stopAtEntry": false,"cwd": "${workspaceFolder}","environment": [],"externalConsole": false,"MIMode": "gdb","miDebuggerPath": "D:\\mingw64\\bin\\gdb.exe","setupCommands": [{"description": "为 gdb 启用整齐打印","text": "-enable-pretty-printing","ignoreFailures": true}],"preLaunchTask": "C/C++: g++.exe build active file"}]
}

c_cpp_properties.json

{"configurations": [{"name": "Win32","includePath": ["${workspaceFolder}/**","D:/opencv/build/include","D:/opencv/build/include/opencv","D:/opencv/build/include/opencv2"],"defines": ["_DEBUG","UNICODE","_UNICODE"],"compilerPath": "D:\\mingw64\\bin\\gcc.exe","cStandard": "c11","cppStandard": "c++17","intelliSenseMode": "clang-x64"}],"version": 4
}

tasks.json

{"tasks": [{"type": "shell","label": "C/C++: g++.exe build active file","command": "D:\\mingw64\\bin\\g++.exe","args": ["-g","${file}","-o","${fileDirname}\\${fileBasenameNoExtension}.exe","-I","D:/opencv/build/include","-I","D:/opencv/build/include/opencv","-I","D:/opencv/build/include/opencv2","-L","D:/opencv/build/x64/MinGW/lib","-l", "libopencv_core348","-l", "libopencv_imgproc348","-l", "libopencv_video348","-l", "libopencv_ml348","-l", "libopencv_highgui348","-l", "libopencv_objdetect348","-l", "libopencv_flann348","-l", "libopencv_imgcodecs348","-l", "libopencv_photo348","-l", "libopencv_videoio348"],"options": {"cwd": "${workspaceFolder}"},"problemMatcher": ["$gcc"],"group": {"kind": "build","isDefault": true}}],"version": "2.0.0"
}

到这里差不多就OK了，执行一下exe
