// DO NOT PUT #pragma once or include guard check here
// This header is designed to be able to be included multiple times

// 3rd party code. Please make sure to always use this paired with the RedefineCompilerMacros.h header.
//
// ex.
//
// #include "UndefineCompilerMacros.h"
// #include "Some3rdParty.h"
// #include "RedefineCompilerMacros.h"
