OsgEarth开发笔记（四):Qt5.15.2在QtCreator集成Osg3.6.3 OsgEarth3.1 OsgQt的vs2019x64版本开发环境搭建

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：

？

？

？填入其他夸脱路径：

？

？

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)

模块化
