[gtkmm] Compiling my first gtkmm program - HELP!!

[Maya <EscalanteCanada netscape net>]

Hi folks!!
I have been trying to compile an example program included in the gtkmm 
documentation, but for some reason I am having a lot of  errors and/or 
warnings displayed.
The Makefile I wrote is this:
------
CPP=g++
LDLIBS=`pkg-config gtkmm-2.0 --libs`
CFLAGS= -Wall -g `pkg-config gtkmm-2.0 --cflags --libs`
OBJS = main.o wimm.o
EXEC = wimm.exe

$(EXEC): $(OBJS)
[TAB]    $(CPP) $(OBJS) $(LDLIBS) -o $(EXEC)

main.o: main.cpp wimm.hpp
[TAB]    $(CPP) $(CFLAGS) -c main.cpp

wimm.o: wimm.hpp
[TAB]    $(CPP) $(CFLAGS) -c wimm.cpp
  
clean:
   rm -f $(OBJS)
   rm -f $(EXEC)

PHONY: clean
----
{I am writing the word [TAB] so that you know that I have added the tab 
there, the original Makefile does not include that word}
After typing 'make' this are the warnings and errors I get:

What am I doing wrong? How can I solve this problem?
