SDL backend dependencies missing?

[Xhyub]

Hello,

Running make for one examples found in the repo, gives me:

g++ -std=c++11 -I../.. -I../../backends -g -Wall -Wformat sdl2-config --cflags -c -o imgui_impl_sdlrenderer.o ../../backends/imgui_impl_sdlrenderer.cpp
../../backends/imgui_impl_sdlrenderer.cpp: In function ‘void ImGui_ImplSDLRenderer_RenderDrawData(ImDrawData*)’:
../../backends/imgui_impl_sdlrenderer.cpp:192:17: error: ‘SDL_RenderGeometryRaw’ was not declared in this scope; did you mean ‘SDL_RenderGetMetalLayer’?
192 | SDL_RenderGeometryRaw(bd->SDLRenderer, tex,
| ^~~~~~~~~~~~~~~~~~~~~
| SDL_RenderGetMetalLayer
make: *** [Makefile:70: imgui_impl_sdlrenderer.o] Error 1

Running debian 11 with vcpkg installed to manage SDL. Have changed header definitions to <SDL2/SDL.h> still no luck, any suggestions?
