// example how to set up OpenGL core context on X11 with EGL
// and use basic functionality of OpenGL 4.5 version

// to compile on Ubuntu first install following packages: build-essential libx11-dev libgl-dev libegl-dev
// then run:
// gcc x11_opengl.c -o x11_opengl -lm -lX11 -lEGL

1. compile dxgi.c & d3d11.c files - these create dxgi.dll and d3d11.dll that allows to dump & replace shaders.

cl.exe /nologo /O2 /W3 /MT dxgi.c /link /DLL /OUT:dxgi.dll /INCREMENTAL:NO kernel32.lib user32.lib
cl.exe /nologo /O2 /W3 /MT d3d11.c /link /DLL /OUT:d3d11.dll /INCREMENTAL:NO kernel32.lib user32.lib d3dcompiler.lib dxguid.lib shlwapi.lib

2. put dxgi.dll and d3d11.dll files next to ChildrenOfMorta.exe

3. create d3d11_shaders folder next to ChildrenOfMorta.exe and put ps_b1c05ceb9ca8a14c.hlsl into this folder.
