What version of OpenSceneGraph I should build OsgEarth with?
I tried to build different combinations of OpenSceneGraph and OsgEarth versions and got cmake errors or compiler errors, for example building osgearth-2.8 with OpenSceneGraph-3.5.6 results in compiler errors. But if I get the latest versions of both OpenSceneGraph and OsgEarth they build fine. So, what version of OpenSceneGraph I should build OsgEarth with?
