#!/bin/bash

# the reason for this patch's existance is that the latest (at time of writing) SRanipal plugin 
# source code has an enum "FrameworkStatus::ERROR" in Source/SRanipalEye/Public/SRanipalEye_Framework.h
# which directly conflicts with some lingering #defines from UE4's WebRTC or CEF3 code which include a
# #define ERROR 0, this unfortunately gets propogated through the build and causes syntax errors when
# trying to compile SRanipal directly. The easiest fix with least ramifications is to simply rename the
# SRanipal's FrameworkStatus::ERROR variable to something specific like FrameworkStatus::ERROR_SRANIPAL
