Introduction
CMake is a cross-platform build system which generates build files for use by native build systems for different platforms. On UNIX-like systems it generates makefiles. For IceCube? Offline Software it replaces offline-mk. CMake provides easier per-project build configuration, a more standard build environment across different platforms, additional testing infrastructure, and out-of-source compilation.
All documentation is hosted elsewhere now (and kept up to date!)
