How to build things with Cmake

1. open a console and navigate to the folder with CMakeLists.txt
2. do 'which cmake' to make sure you have cmake available (it should show the path to the cmake program executable)
3. make a folder next to CMakeLists.txt (in same directory) and call it 'build' or something
4. go into that folder like 'cd build'
5. do 'cmake ..'
