+Description: dear imgui (AKA ImGui), is a bloat-free graphical user interface 
+library for C++. It outputs optimized vertex buffers that you can render anytime
+in your 3D-pipeline enabled application. It is fast, portable, renderer agnostic
+and self-contained (no external dependencies).

+Description: ODE is a free, industrial quality library for simulating 
+articulated rigid body dynamics - for example ground vehicles, legged creatures,
+and moving objects in VR environments. It is fast, flexible, robust and platform
+independent, with advanced joints, contact with friction, and built-in collision
+detection.
