# - Find JeMalloc library
# Find the native JeMalloc includes and library
# This module defines
#  JEMALLOC_INCLUDE_DIRS, where to find jemalloc.h, Set when
#                        JEMALLOC_INCLUDE_DIR is found.
#  JEMALLOC_LIBRARIES, libraries to link against to use JeMalloc.
#  JEMALLOC_ROOT_DIR, The base directory to search for JeMalloc.
#                    This can also be an environment variable.
#  JEMALLOC_FOUND, If false, do not try to use JeMalloc.
#
# also defined, but not for general use are
#  JEMALLOC_LIBRARY, where to find the JeMalloc library.
