5 # Created : 2013

8 # Instruction : See 'make help'

10 # make builds the release versions for the

11 # current architechture

12 # make clean delete intermediate release object files

13 # and library and executable

14 # make DEBUG=1 builds the debug version for the current

15 # architechture

16 # make clean DEBUG=1 deletes intermediate debug object files

17 # and the library and executable

18 #

19 # Output : Relative to the directory this Makefile lives in, libraries

20 # and executables are built at the following locations

21 # depending upon the architechture of the system you are

22 # running:

23 #

24 # ./LibOVR/Lib/Linux/Debug/i386/libovr.a

25 # ./LibOVR/Lib/Linux/Debug/x86_64/libovr.a

26 # ./LibOVR/Lib/Linux/Release/i386/libovr.a

27 # ./LibOVR/Lib/Linux/Release/x86_64/libovr.a

28 # ./Samples/OculusWorldDemo/Release/OculusWorldDemo_i386_Release
