OpenCV mingw-make32 Makefile:12: *** multiple target patterns. Stop

I installed mingw gcc, g++ compiler. I downloaded the opencv source for 2.4.10. Then I used the following commands to compile the source:

cmake -G "MinGW Makefiles" -D CMAKE_CXX_COMPILER=mingw32-g++.exe -D CMAKE_MAKE_PROGRAM=mingw32-make.exe ..

mingw32-make

mingw32-make install

Then I added the lib to my windows PATH. I use the following Makefile to compile the code but I get an error(using windows cmd):

CC = gcc
CFLAGS = -g -Wall

SRCS = main.cpp input_main.cpp image_manuplation.cpp track_object.cpp
PROG = main.exe

OPENCV = -I"C:\Users\Username\Documents\opencv\sources\release\install\include" -I. -L"C:\Users\Username\Documents\opencv\sources\release\install\x86\mingw\lib" -lopencv_calib3d2410 -lopencv_contrib2410 -lopencv_core2410 -lopencv_features2d2410 --lopencv_flann2410 -lopencv_gpu2410 -lopencv_highgui2410 -lopencv_imgproc2410 -lopencv_legacy2410 -lopencv_ml2410 -lopepncv_nonfree2410 -lopencv_objdetect2410 -lopencv_ocl2410 -lopencv_photo2410 -lopencv_stitching2410 -lopencv_superres2410 -lopencv_ts2410 -lopencv_video2410 -lopencv_videostab2410

all : $(PROG)

$(PROG) : $(SRCS)
    $(CC) $(CFLAGS) -o $(PROG) $(SRCS) $(OPENCV)

clean:
    @del $(PROG)

I get the following error:

Makefile:12: *** multiple target patterns.  Stop.

Would someone know how to fix the error? I did similar thing on Ubuntu and it works. Thank you

Line 12 is the recipe line. I believe you haven't started that line with a TAB character. Make requires a real TAB, not just spaces. Make sure your editor is capable of inserting a TAB character and doesn't "helpfully" convert it to spaces for you when you save.
