You can add different directories to find_library. To use this library call cmake by cmake -DFOO_PREFIX=/some/path ....

find_library( CPPUNIT_LIBRARY_DEBUG NAMES cppunit cppunit_dll cppunitd cppunitd_dll
            PATHS   ${FOO_PREFIX}/lib
                    /usr/lib
                    /usr/lib64
                    /usr/local/lib
                    /usr/local/lib64
            PATH_SUFFIXES debug )

find_library( CPPUNIT_LIBRARY_RELEASE NAMES cppunit cppunit_dll
            PATHS   ${FOO_PREFIX}/lib
                    /usr/lib
                    /usr/lib64
                    /usr/local/lib
                    /usr/local/lib64
            PATH_SUFFIXES release )

if(CPPUNIT_LIBRARY_DEBUG AND NOT CPPUNIT_LIBRARY_RELEASE)
    set(CPPUNIT_LIBRARY_RELEASE ${CPPUNIT_LIBRARY_DEBUG})
endif(CPPUNIT_LIBRARY_DEBUG AND NOT CPPUNIT_LIBRARY_RELEASE)

set( CPPUNIT_LIBRARY debug     ${CPPUNIT_LIBRARY_DEBUG}
                    optimized ${CPPUNIT_LIBRARY_RELEASE} )

# ...
target_link_libraries(foo ${CPPUNIT_LIBRARY})
