imogui - draw on overlays using imgui

A GUI library which hooks existing overlays to draw on them using imgui (https://github.com/ocornut/imgui). The project includes hookFTW (a hooking library) as a submodule which in turn includes zydis (a disassembler) as a submodule.

Setting up

1. Clone including submodules:

git clone --recursive https://github.com/Fahersto/imogui.git

2. Build the library using CMAKE.

Using imogui

You can create any imgui element or draw primitives using the passed imogui::Renderer inside the provided OnDraw callback:

void OnDraw(imogui::Renderer* renderer)

Example implementations are provided in src/Examples.
