# Filename    : Makefile
# Content     : Makefile for building linux version of: libovr
# 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 library file
#               make DEBUG=1        builds the debug version for the current
#                                   architechture
#               make clean DEBUG=1  deletes intermediate debug object files 
#                                   and the library file
#
# Output      : Relative to the directory this Makefile lives in, libraries
#               are built at the following locations depending upon the
#               architechture of the system you are running:
#
#               ./Lib/Linux/Debug/i386/libovr.a
#               ./Lib/Linux/Debug/x86_64/libovr.a
#               ./Lib/Linux/Release/i386/libovr.a
#               ./Lib/Linux/Release/x86_64/libovr.a
