This is a little off-topic, but you might find that GNU make has had a
dozen years of optimization for doing this kind of stuff easily and
concisely:

--- makefile ---
default: test

TEST_H = $(wildcard *_test.h)
TEST_E = $(TEST_H:.h=)

exe: $(TEST_E)

test: exe
  for t in $(TEST_E); do ./$$t; done

%.o: %.cpp
  c++ -c -o $@ $<

%_test.cpp: %_test.h
  cxxtest.pl -o $@ $<

%_test: %_test.o %.o
   c++ -o $@ $^
----------------

This makefile enforces your naming convention, that the unit test for
BAR are in BAR_test.h, and the source is in BAR.cpp

I took the liberty of running the tests by default, as all good
makefiles should do.
