It does already: no need for convincing.

This is not right. The $* variable matches the stem of the pattern.
The stem of the pattern here is something like "Employee", the stem is
NOT "emp/Employee". You can see this easily be changing your rule to
print out the values of the various automatic variables.
If you want this to work you need to use the $@ and $< variables, like
so:
%.o: %.cpp
$(COMPILE.cc) $< -o $@
Hope this helps...
