Description
The core of Dear ImGui is self-contained within a few platform-agnostic files which you can easily compile in your application/engine. They are all the files in the root folder of the repository (imgui*.cpp, imgui*.h). No specific build process is required. You can add the .cpp files into your existing project.
Backends for a variety of graphics API and rendering platforms are provided in the backends/ folder, along with example applications in the examples/ folder. See the Integration section of this document for details. You may also create your own backend. Anywhere where you can render textured triangles, you can render Dear ImGui.
After Dear ImGui is set up in your application, you can use it from _anywhere_ in your program loop
