cimgui?

Hi, I'm new to Zig. Why do you import cimgui instead of imgui directly? Is it because of `CIMGUI_DEFINE_ENUMS_AND_STRUCTS` maybe? Could you elaborate on that, please? Thank you!

The issue mentions the cimgui import, imgui, and CIMGUI_DEFINE_ENUMS_AND_STRUCTS but names no files, tests, or documentation entry point. First locate where the import is defined and where project setup is documented; done means the reason for choosing cimgui over imgui is explained in a discoverable project document.
