# Filename : Makefile
# Content : Makefile for building linux OculusWorldDemo
# Created : 2013
# Authors : Simon Hallam and Peter Giokaris
# Copyright : Copyright 2013 OculusVR, Inc. All Rights Reserved
# Instruction : The g++ compiler and stdndard lib packages need to be
# installed on the system. Navigate in a shell to the
# directory where this Makefile is located and enter:
#
# make builds the release version for the
# current architechture
# make clean delete intermediate release object files
# and the executabe file
# make DEBUG=1 builds the debug version for the current
# architechture
# make clean DEBUG=1 deletes intermediate debug object files
# and the executable file
#
# Output : Relative to the directory this Makefile lives in, executable
# files get built at the following locations depending upon the
# architechture of the system you are running:
#
# ./Release/OculusWorldDemo_i386_Release
# ./Release/OculusWorldDemo_x86_64_Release
# ./Release/OculusWorldDemo_i386_Debug
# ./Release/OculusWorldDemo_x86_64_Debug
