【vcpkg+cmake+qt的vs2019工程框架搭建】

vcpkg+cmake+qt的vs2019工程框架搭建 概要

cmake工程已经应用非常普及，vcpkg可以很方便的应用第三方库，省去了自己编译第三方库的时间，本文档说明基于cmake+qt+vcpkg的多项目结构搭建。

项目目录结构

|—games #游戏集根目录
cmakefilelist.txt #根cmake文件
|—build #cmake生成vs2019的工程目录
|—source #源代码根目录， 可以包含多个独立的游戏
cmakefilelist.txt #源代码cmake文件
|—coin #翻金币游戏
cmakefilelist.txt #翻金币cmake文件
|—snake # 贪吃蛇游戏

各个cmakefilelist文件说明 根cmakefilelist.txt

安装第三方库管理工具vcpkg

略，自行baidu

vcpkg安装qt相关包

vcpkg install qt5-base:x64-windows-static
vcpkg install qt5-translations:x64-windows-static
vcpkg install qt5-winextras:x64-windows-static

在build目录中生成vs2019工程

cmake … -DCMAKE_TOOLCHAIN_FILE=C:\vcpkg\scripts\buildsystems\vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-windows-static

vs2019打开工程文件编译 —done
