Ubuntu20.04下OMNeT++配置osgEarth失败求助

我正尝试在OMNeT中使用OpenSceneGraph与OSGEarth模块，按照OMNeT安装指南执行了以下命令安装依赖包：

sudo apt-get install openscenegraph-plugin-osgearth libosgearth-dev    
sudo apt-get install libopenscenegraph-dev

修改OMNeT++根目录下的configure.user文件后运行./configure，出现如下错误：

checking for osgEarth with CFLAGS=" -fPIC  -fno-omit-frame-pointer  " LIBS=" -Wl,--export-dynamic   -losgEarth -losgEarthUtil -lgeos_c "... no
configure: error: Cannot find osgEarth 2.7 or later. Set WITH_OSGEARTH=no in configure.user to disable this feature or install an up to date version of osgEarth.

我已尝试卸载重装所有相关包及OMNeT++，但问题依旧。
