Setting up your own osgART project
From ARToolworks support library
Where to begin
The easiest way to set up your own osgART project is to copy the structure of the osgART simple example, which can be found in the directory "osgARTTest" inside "src" at the top-level of the osgART distribution.
You will also need to copy the project settings for your chosen platform's build system.
Operating system specifics
Mac OS X
One key addition on Mac OS X is the preprocessor definition used to tell OpenSceneGraph to use the AGL (Apple Mac OS X OpenGL)-specific implementation of Producer. This needs to be added to the build settings of your application. Use the image below as a guide.
