Using Boost with Makefile/Missing Separator

I am brand new to make files and Boost, and I'm trying to follow this tutorial, specifically Makefile4.

I only have two source files, namely S1.cpp, where main.cpp is located, and GaussQuadrature.h. Now, GaussQuadrature.h also uses a Boost file, so (as far as I know) I must tell the compiler where Boost is located, which is up two directories from where my source files are. My makefile is

CC=g++
CFLAGS=-o2 -std=c++0x
DEPS = GaussQuadrature.h
OBJ = S1.o

%.o: %.cpp $(DEPS)
     $(CC) -c -o $@ $< $(CFLAGS)

S1: $(OBJ)
    $(CC) -o $@ $^ $(CFLAGS) S1.o -o S1 -I ../../boost_1_55_0

When I run the make command I get the error 

makeS1:7: *** missing separator.  Stop.

I've read this is most commonly due to missing tabs for the command (and it's interesting that when I hit 'tab' that the two commands are indented differently above), but even when I change those to

%.o: %.cpp $(DEPS)
\t$(CC) -c -o $@ $< $(CFLAGS)

S1: $(OBJ)
\t$(CC) -o $@ $^ $(CFLAGS) S1.o -o S1 -I ../../boost_1_55_0

I get the same error.

Other than fixing this error, what is proper way to include the Boost directory in a makefile, or is there a way around including it altogether? Thanks!

It has nothing to do with Boost. Makefiles require tabs

http://www.delorie.com/djgpp/v2faq/faq22_17.html

Unlike most other DOS Make programs which accept any whitespace character at the beginning of a command in a rule, GNU Make insists that every such line begins with a TAB. (Most other Unix Make programs also require TABs, and the Posix standard requires it as well.) Make sure that the line whose number is printed in the error message (in this case, line 10) begins with a TAB.
