You cannot have sources and objects in separate directories with suffix
rules.
If you want to do this you need to use pattern rules.
%.o: $(SRC)/%.cpp $(INCL)/%.h
...

You should not use a C compiler to build C++ files.
Use $(CXX) and $(CXXFLAGS). $(CC) is a C compiler, and $(CPPFLAGS) are
flags to the C preprocessor (-I, -D, etc.)
dp> node.o: $(SRC)/$(@:.o=.cpp) $(INCL)/$(@:.cpp=.h)
dp> $(CC) $(CPPFLAGS) $(SRC)/$(@:.o=.cpp)
This is not correct. Automatic variables like $@, etc. are defined only
within the context of the command script; they have no value in the
prerequisite list.
Since $@ has no value, your rule above is equivalent to:
node.o: $(SRC)/ $(INCL)/
...
which makes your .o depend on the directories--and explains the strange
rebuild behavior you're seeing.
