otherwise it's always true, even if the libaries are not found. also the cmake output will be wrong without this change: without this change, it is: -- Found gperftools: GPERFTOOLS_TCMALLOC_LIBRARY;GPERFTOOLS_TCMALLOC_MINIMAL_LIBRARY;GPERFTOOLS_PROFILER_LIBRARY (found version "2.5.93") with this change, it would be: -- Found gperftools: /tmp/gperf/lib/libtcmalloc.so (found version "2.5.93") Signed-off-by: Kefu Chai <kchai@redhat.com>
