+#  find_package(jemalloc)
+#
+# Variables used by this module, they can change the default behaviour and need
+# to be set before calling find_package:
+#
+#  JEMALLOC_HOME -
+#   When set, this path is inspected instead of standard library locations as
+#   the root of the jemalloc installation.  The environment variable
+#   JEMALLOC_HOME overrides this veriable.
+#
+# This module defines
+#  JEMALLOC_INCLUDE_DIR, directory containing headers
+#  JEMALLOC_SHARED_LIB, path to libjemalloc.so/dylib
+#  JEMALLOC_FOUND, whether flatbuffers has been found
