How would the rules in the below Makefile be written for the below c++ test case? fill the section that says "# Need a rule to build objects"

//Test case
	#define CATCH_CONFIG_MAIN
	#include
	#include "catch/catch.hpp"
	#include "../foo.hpp"
	#include "../bar.hpp"
	#include "../baz.hpp"
	TEST_CASE("Test Classes. PASS.")
	{
	REQUIRE (Foo.GetMagicNumber() == 12);
	Bar b = Bar("Hello");
	REQUIRE (b.GetString() == "Hello");
	Baz *baz = new Baz(90.0 / 9);
	REQUIRE (baz->GetValue() > 9.999 && baz->GetValue() < 10.0001);
	}
	// Compile & run:
	// make clean test

//Makefile
	CXX = g++
	CXXFLAGS = -std=c++11 -Wall
	OBJECTS = # list of .o files. One for each class
	# Need a rule to build objects
	testBuild: main
	$(CXX) $(CXXFLAGS) -Itest/catch/catch.hpp -o test/TestCase $(OBJECTS) test/TestCase.cpp
	test: clean testBuild
	test/TestCase --success
	clean:
	$(RM) *.o *.gch main test/TestCase
