[Maciej Sumiński <maciej.suminski@xxxxxxx>]

When you build a program, do you always go through its build manual or
do you start with 'cmake .. && make'? I think there is no point
enforcing an optional dependency. Another good solution would be to
autodetect libngspice and enable the simulator if it is available.
