*********************************************************************************************************
NEW: Parameters for making siftgpu library can be changed in makefile. 
	Look at the top part of makefile for details. 
*********************************************************************************************************



1. DEPENDING LIBRARIES
*********************************************************************************************************
The list of required libraries for Linux is 
libGLEW.a	libglut.so 	libIL.so -> libIL.so.1 		libIL.so.1	

optional libaries: 
	libCudart.so 

Those libraris may also be dependent on other libraries, and you may need to download them yourself. 
You also need to handle the compatibility of those libraies yourself. 

Get those libraries either in the system default path or ./bin here before compiling. 
********************************************************************************************************


2. MAC OS
*********************************************************************************************************
For Mac User, the libraries are 
GLUT.framework		OpenGL.framework	

libGLEW		libIL 	libCudart (optional)
*********************************************************************************************************



3. SSE SETTING
***************************************************************************************************
Please change the compiler options according to your CPU to enable SSE if the default setting doesn't work.

siftgpu_sse_options = -march=(cpu_type) -mfpmath=sse

SSE is only used in OpenGL-based imiplementations to speed up the descriptor normalization,
you can delete them from CFLAGS if you are using only CUDA.
****************************************************************************************************



4. OUTPUT
*******************************************************************************************************
The list of output binaries is
./bin/libsiftgpu.a	./bin/libsiftgpu.so
./bin/TestWinGlut	./bin/SimpleSIFT 	./bin/speed 	./bin/server_siftgpu


If you want to run the stuff with any .so files in ./bin, don't forget to add . to LD_LIBRARY_PATH/
DYDL_LIBRARY_PATH. For example:  export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:.
