Together with Manuel Herrmann I gave a short presentation of the CMake buildsystem at the Berlin C++ UserGroup on 21.01.2014.
The slides are online, you'll find them here: CMake.pdf
The first sample project was this OpenGL project from Manuel.
The second sample was a small math library called smallcalc I wrote for µoscalc on iPad, demonstrating cross platform compilation to iOS and Android.
Thanks to Manuel.
