# Filename : Makefile
# Content : Makefile for building linux libovr and 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 versions for the
# current architechture
# make clean delete intermediate release object files
# and library and executable
# make DEBUG=1 builds the debug version for the current
# architechture
# make clean DEBUG=1 deletes intermediate debug object files
# and the library and executable
#
# Output : Relative to the directory this Makefile lives in, libraries
# and executables are built at the following locations
# depending upon the architechture of the system you are
# running:
#
# ./LibOVR/Lib/Linux/Debug/i386/libovr.a
# ./LibOVR/Lib/Linux/Debug/x86_64/libovr.a
# ./LibOVR/Lib/Linux/Release/i386/libovr.a
# ./LibOVR/Lib/Linux/Release/x86_64/libovr.a
# ./Samples/OculusWorldDemo/Release/OculusWorldDemo_i386_Release
# ./Samples/OculusWorldDemo/Release/OculusWorldDemo_x86_64_Release
# ./Samples/OculusWorldDemo/Release/OculusWorldDemo_i386_Debug
# ./Samples/OculusWorldDemo/Release/OculusWorldDemo_x86_64_Debug
