Re: [osg-users] [build] how to build basicGeometry example?

Hi Thomas, you need to do a couple of things, first take a copy of the CMakeModules folder of OSG itself : http://www.openscenegraph.org/projects/osg/browser/OpenSceneGraph/trunk/CMakeModules Then you need to tell CMake via your CMakeLists.txt where to find those set(CMAKE_MODULE_PATH
