Using rlImGui from C.

[JeffM2501]

You can use ImGui and rlImGui from C, you just need to use the cimgui wrapper .https://github.com/cimgui/cimgui

You build ImGui, cImGui, and rlImGui into a single static library using C++ that you link into your C program.
You do not need to program in C++, you just need to build the library using it.
This is an example project that does that, allowing you to use all of ImGui from C.
