That's kind of a weird question.

You know which libraries you need to link to because you're using classes that 
reside in them.

How do i know that I need to link to QtWidget? 
Because you're using QLabel and the documentation says so.

How do you know that I need to link to KConfigWidgets?
Because you're using KColorScheme and the documentation says so.
