#  GOOGLE_PERFTOOLS_FOUND, If false, do not try to use Google perftools.
# also defined for general use are
#  TCMALLOC_LIBS, where to find the tcmalloc libraries.
#  TCMALLOC_STATIC_LIB, path to libtcmalloc.a.
#  TCMALLOC_SHARED_LIB, path to libtcmalloc's shared library
#  PROFILER_LIBS, where to find the profiler libraries.
#  PROFILER_STATIC_LIB, path to libprofiler.a.
#  PROFILER_SHARED_LIB, path to libprofiler's shared library
