Problems linking irrlicht

[Redhawk18]

Hi, I was trying to package this project for nixos and I ran into a problem of being unable to include the needed files from irrlicht, It seems like this file is included from here

Linking clzma
libeffect.cpp
==== Building ygoprodll (debug_x64) ====
Creating ../obj/x64/Debug/ygoprodll
CConfigMap.cpp
In file included from ../gframe/CGUISkinSystem/CConfigMap.cpp:1:

libduel.cpp

I tried setting the cflags with the following command, but I'm not sure if this project even uses cflags. export CFLAGS="-I${irrlicht}/include/irrlicht/*"
