前言
本篇非常麻烦，博主用QtCreator作为IDE，因为Osg3.6.3放弃对osgQt的支持，集成起来比较繁琐。
前提
基于前面三篇的基础上，才可以进行本篇。
Demo演示：Qt5.15.2+OSG3.6.3+OsgEarth3.1的QtCreator下的msvc2019x64版本

osgQt编译
步骤一：下载解压
步骤二：CMake配置
步骤三：CMake配置添加osg环境
步骤四：CMake配置添加Qt环境
步骤五：CMake修改CMakeLists文件内容：
还是出现错误：
检查，并未发现错误
继续深入
有一个路径填错了： 
过了，继续配置：
填入其他Qt路径：
步骤六：配置通过
步骤七：生成成功
步骤八：打开工程，进行编译
编译各种问，尝试过多次后放弃，看其他博客是可以的。
（后面的复杂，博主直接修改源码开始移植过去，直接加入工程方式，过程比较艰难，如果能编译好osgQt是最好的，改源码问题较多，需要的可联系博主获取，但是不免费，尊重劳动成果，禁止白嫖）
