I think you are trying to solve a problem that Make already solved for 
you: it knows how to compile C++ files, so you don't need to tell it.  
What you *do* need to tell Make is the dependencies.

So something like this should do:

  all: $(ONE_C:.cpp=.o) $(TWO_C:.cpp=.o)

  $(ONE_C:.cpp=.o): $(ONE_DEP)
  $(TWO_C:.cpp=.o): $(TWO_DEP)

If you need to use non-default compiler options, like -g or -O2, set the 
value of the variables CFLAGS, CPPFLAGS, etc.

The Make manual includes a section which lists all the built-in rules, 
together with the variables (like CFLAGS above) that affect every rule.
