How to do this feature? (What's the name of this feature?)

Question

When I built x265 today, I found a fancy feature as the following picture.

Here comes the question, what can the feature be named? And how can we realize this feature?

ps. Forgive me for the helpless title and tags. It's a great favor if someone can help me to tag this question correctly.

Answer 1

This "feature" is ccmake program.

Aside from normal cmake functionality it provides possibility to edit CMake Cache with curses interface.
