Makefile with different rules for .o generation

If I have a rule like this in my make file:

CC = g++
CFLAGS = -Wall
COMPILE = $(CC) $(CFLAGS) -c

src = A.cpp \
      main.cpp

test_src = Test.cpp 
test = testAll

OBJFILES := $(patsubst %.cpp,%.o,$(src))
TEST_OBJS := $(patsubst %.cpp,%.o,$(test_src))

%.o: %.cpp
    $(COMPILE) -I UnitTest++/src -LUnitTest++/ -l UnitTest++ -o $@ $<

I end up including and linking UnitTest++ to non test files such as main and A.cpp How can I make only make Test classes link with the test libraries?

Specify which files your rule applies to:

$(TEST_OBJS): %.o: %.cpp
    $(COMPILE) -I UnitTest++/src -LUnitTest++/ -l UnitTest++ -o $@ $<
