IconCast is the name of a close-sourced app I'm publishing that makes money, and
AppIconSetGen, an open source library under the MIT license made by someone else that I made some changes to (which is also open source and under the MIT license), would the copyright notice that could be shown by pressing the "About IconCast" button under the "IconCast" menu when the app is focused be valid?

Do I have to say how
AppIconSetGen is under the MIT license? Do I have to include a copy of the MIT license? How would I do it?
Thank you for clearing things up for me.
