主要内容简介:

将使用第三方构建工具premake: https://github.com/premake/premake-core来自动生成平台项目文件

在premake: https://github.com/premake/premake-core/releases/tag/v5.0.0-alpha15下载最新版本 premake-5.0.0-alpha15-windows.zip

将premake-5.0.0-alpha15-windows.zip解压到 项目根目录/vendor/bin/premake/下

在项目根目录下 新建文本文件 命名为premake5.lua

premake5.lua

workspace "Hazel" --解决方案名称

    filter "system:windows"--windows平台的配置

        runtime "Debug"
        symbols "on"

在项目根目录下 新建文本文件 命名为GenerateProjects.bat

GenerateProjects.bat

call vendor\bin\premake\premake5.exe vs2019
pause

双击执行GenerateProjects.bat即可 自动生成工程

打开vs build工程，注意第一遍可能由于目录还没生成 导致自定义的拷贝dll命令失败， 重新执行一次即可
