Thanks Chaitanya,

I modified as your suggestion. But, still got the error (GEOS support not enable) when executing the program.
About building GEOS, if I only add two first lines, the process will be sucessful:

1. GEOS_DIR = C:/geos-3.3.5
2. GEOS_LIB = $(GEOS_DIR)/src/geos_c_i.lib

if I add third line, the building process will get errors

3. GEOS_CFLAGS = -I$(GEOS_DIR)/capi -I$(GEOS_DIR)/include/geos -DHAVE_GEOS 


LINK : fatal error LNK1181: cannot open input file 'ogr\ogrsf_frmts\ogrsf_frmts.
NMAKE : fatal error U1077: '"C:\Program Files\Microsoft Visual Studio 10.0\VC\BI
N\lib.EXE"' : return code '0x49d'

Thanks and regards,

The environment variables can be set at the command prompt temporarily using 

SET LD_LIBRARY_PATH=C:\path\to\gdal\libraries
SET GDAL_DATA=C:\path\to\gdal\libraries\data You can set them in the project settings in VC++. I don't know how.
You can also set them system wide at MyComputer->Settings.
