I found what was wrong. The problem is that "make cannot use the
appropriate path to the source if you hardcode the filename" [1].
When automatic variables are used as shown below, the problem is
solved.
CC = g++
VPATH = .:../../parent/comp01
CXXFLAGS = -ggdb -I ../../parent/comp01
OBJECTS = main.o Factory.o Context.o FactoryEx.o ContextEx.o
comp01: $(OBJECTS)
$(CC) $(OBJECTS) -o $@
clean:
rm *.o comp01
