+# FindLINENOISE
+# --------
+#
+# Find the native LINENOISE includes and library.
+#
+# IMPORTED Targets
+# ^^^^^^^^^^^^^^^^
+#
+# This module defines :prop_tgt:`IMPORTED` target ``LINENOISE::LINENOISE``, if
+# LINENOISE has been found.
+#
+# Result Variables
+# ^^^^^^^^^^^^^^^^
+#
+# This module defines the following variables:
+#
+# ::
+#
+#   LINENOISE_INCLUDE_DIRS   - where to find linenoise.h, etc.
+#   LINENOISE_LIBRARIES      - List of libraries when using linenoise.
+#   LINENOISE_FOUND          - True if linenoise found.
+#
+# Hints
+# ^^^^^
+#
+# A user may set ``LINENOISE_ROOT`` to a linenoise installation root to tell this
+# module where to look.
