win10下VSCode配置opencv4.4.0（超詳細教程，親測有效）

VSCode作為一個輕量級的編程軟體，無論在界面、記憶體占用和速度等方面都完勝VS，但用vscode來寫opencv代碼需要自己編譯OpenCV（如果是VS安裝opencv則不需要自己編譯opencv，因為在opencv的官網上就有編譯好的檔案），主要用到MinGW-w64和CMake工具，前前后后折騰了好久，終于配好了opencv的環境，寫篇博客，一是為了怕自己忘了，又要重新學，二是分享一下自己的經驗，主要參考兩篇博客：

1.安裝MinGW-w64

MinGW-w64下載地址

https://github.com/huihut/OpenCV-MinGW-Build

(參考博客：https://www.cnblogs.com/kensporger/archive/2020/02/19/12320622.html）

配置環境變數

2.安裝CMake

CMake下載地址：

https://cmake.org/download/

配置環境變數

記得重啟電腦使3個環境變數生效

3.生成MakeFiles

需要去官網下載OpenCV的sources源檔案，如果下載太慢，可以找找百度網盤，或者是國內鏡像網站

https://www.bzblog.online/wordpress/index.php/2020/03/09/opencvdownload/

注意：是下載opencv對應的source源檔案
打開CMake-gui.exe，點擊configure，會出現一些問題，主要是會卡在下載ffmpge檔案，需要改下host檔案，這時只能耐心等待了，再次點擊configure，完成后點generate，

Cmake下載檔案時一次不成功，那就再來一次

4.編譯opencv

CMD到MakeFiles所在檔案夾（shift+右鍵，選擇powershell打開），執行minGW32-make命令，或者使用多執行緒minGW32-make -j 4命令：

編譯程序中可能會出現各種各樣的錯誤，不要急，主要是回傳第三步，去掉勾選，再次點擊configure,generate，

好了，opencv編譯成功，最后只剩下在VSCode中配置opencv了（筒子們，離最后的勝利不遠了，堅持）

編譯完成后記得輸入minGW32-make install完成裝載，這樣才會生成Install檔案夾，

5.VSCode配置
