源码编译安装

前往wxWidgets官网，下载wxWidgets

打开Developer Command Prompt for VS 2022工具，进入 build\msw 目录，编译

1
 nmake /f makefile.vc BUILD=debug SHARED=0 TARGET_CPU=X64

这里我编译了64位debug版的静态库，这里x64和debug两个关键字很重要，你在VS中开发时，也要选择相应的配置

在属性管理器窗口添加wxWidgets目录下的wxwidgets.props文件

这里我们还需要额外注意一下，因为我们跑的是GUI程序，所以需要在项目的属性中，把项目设置成窗口

跑个简单的程序，hello.cpp
