+# ------------
+#
+# This module finds the `LTTng-UST <http://lttng.org/>`__ library.
+#
+# Imported target
+# ^^^^^^^^^^^^^^^
+#
+# This module defines the following :prop_tgt:`IMPORTED` target:
+#
+# ``LTTng::UST``
+#   The LTTng-UST library, if found
+#
+# Result variables
+# ^^^^^^^^^^^^^^^^
+#
+# This module sets the following
+#
+# ``LTTNGUST_FOUND``
+#   ``TRUE`` if system has LTTng-UST
+# ``LTTNGUST_INCLUDE_DIRS``
+#   The LTTng-UST include directories
+# ``LTTNGUST_LIBRARIES``
+#   The libraries needed to use LTTng-UST
+# ``LTTNGUST_VERSION_STRING``
+#   The LTTng-UST version
+# ``LTTNGUST_HAS_TRACEF``
+#   ``TRUE`` if the ``tracef()`` API is available in the system's LTTng-UST
+# ``LTTNGUST_HAS_TRACELOG``
+#   ``TRUE`` if the ``tracelog()`` API is available in the system's LTTng-UST
