Your installation of the MeVisLab SDK contains the sources of selected modules and several additional example modules. Those example modules are located within the MeVisLab.app bundle in the /Contents/Packages/MeVisLab/Examples/Sources subdirectories. They are a great source of information. However, not all of the included source code projects are ready to compile. Some of the projects require modifications to the project settings and/or additional files that may not be included.
