ADD_LIBRARY creates a new library. LINK_LIBRARIES is more or less 
deprecated. So how about the following: 
 
PROJECT(testing) 
 
ADD_EXECUTABLE(main main.cpp HelloCPPUnitTest.cpp ) 
 
FIND_LIBRARY(CPPUNIT_LIBARY NAMES cppunit 
  PATHS /usr/lib /usr/local/lib) 
IF (CPPUNIT_LIBRARY) 
  TARGET_LINK_LIBRARY(main ${CPPUNIT_LIBRARY}) 
ENDIF (CPPUNIT_LIBRARY) 
 
Bye
