osg qt5.15 osg3.6.3 osgEarth3.1 编译爬山

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，看其他博客是可服务器托管网以的。

（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）
