Eepp - Entropia Engine++

Just found this while clicking away. I’ve searched the forum and saw no mention of it. Developer claims it works in Haiku… anyone familiar with this here?

GitHub - SpartanJ/eepp: eepp is an open source cross-platform game and application development framework heavily focused on the development of rich graphical user interfaces.

Some modules like UI and Windowing seem redundant for Haiku, but others like Graphics/OpenGL, Networking, Maps look interesting imho.
