# - Find Tcmalloc library
# Find the native Tcmalloc includes and library
# This module defines
#  TCMALLOC_INCLUDE_DIRS, where to find tcmalloc.h, Set when
#                        TCMALLOC_INCLUDE_DIR is found.
#  TCMALLOC_LIBRARIES, libraries to link against to use Tcmalloc.
#  TCMALLOC_ROOT_DIR, The base directory to search for Tcmalloc.
#                    This can also be an environment variable.
#  TCMALLOC_FOUND, If false, do not try to use Tcmalloc.
#
# also defined, but not for general use are
#  TCMALLOC_LIBRARY, where to find the Tcmalloc library.
