For compiling with backends there is now an example with SDL2 and opengl3 in folder backend_test. It will generate a cimgui_sdl module and a test_sdl executable. You only need to provide SDL_PATH telling cmake where to look for SDL2 cmake installation. For compiling with backends there is now an example with SDL2 and opengl3 in folder backend_test. It will generate a cimgui_sdl module and a test_sdl executable.
