# Usage of this module as follows:
#
# find_package(JeMalloc)
#
# Variables used by this module, they can change the default behaviour and need
# to be set before calling find_package:
#
# JEMALLOC_ROOT_DIR Set this variable to the root installation of
# jemalloc if the module has problems finding
# the proper installation path.
#
# Variables defined by this module:
#
# JEMALLOC_FOUND System has jemalloc libs/headers
# JEMALLOC_LIBRARIES The jemalloc library/libraries
# JEMALLOC_INCLUDE_DIR The location of jemalloc headers
