 If you are familiar with ROS, it is something similar to [catkin](http://wiki.ros.org/catkin/workspaces) or [colcon workspace](https://colcon.readthedocs.io/en/released/user/quick-start.html), but using pure CMake for portability reasons and for customizing the build via CMake options. Furthermore, the `robotology-superbuild` also contains some infrastructure to build **binaries** of the contained projects for some platforms. 
 You can read more about the superbuild concept in [YCM documentation](http://robotology.github.io/ycm/gh-pages/latest/index.html) or in the [related IRC paper](http://lornat75.github.io/papers/2018/domenichelli-irc.pdf).
