(1)vscode官网下载
(2)opencv及其拓展库源码下载
本人下载的是455版本,注意opencv版本与opencv-contrib版本需一致
(3)MinGW下载
(4)cmake下载
(1)解压缩四个安装包,将mingw64的bin添加到环境变量
win+R打开cmd,输入gcc --version,如图所示表明安装成功
(2)vscode编译
cmake-gui.exe
configure
,选择MinGW Makefiles
、Specify native compilers
。Next
,编译器选择,C选择MinGW-w64的bin目录下gcc.exe
,C++则选择g++.exe
Finish
,然后自动开始配置。configure
,配置完成点击generate
。(3).vscode配置
