It is usually a painstaking process to create binary files completely from the source code in order to construct an efficient development environment. There are two different ways to set up the OSG working environment: for beginners, an easy-to-use prebuilt package installer can be obtained from the official OSG website, which may help with installing particular versions of OSG (not all versions have a corresponding installer); and for developers with more experience, there is a more flexible way to work with the OSG source code—using the CMake build system, which is also presented in detail.
