+FindLibOpenFAM
+--------
+
+This module finds the openfam library.
+
+Imported Targets
+^^^^^^^^^^^^^^^^
+
+This module provides the following imported targets, if found:
+
+``LibOpenFAM``
+  The openfam library
+
+Result variables
+^^^^^^^^^^^^^^^^
+
+This module will set the following variables in your project:
+
+``OpenFAM_FOUND``
+  True if the openfam library is found.
+``OpenFAM_INCLUDE_DIRS``
+  Include directories needed to use openfam.
+``OpenFAM_LIBRARIES``
+  Libraries needed to link to openfam.
+
+Cache variables
+^^^^^^^^^^^^^^^
+
+The following cache variables may also be set to help find openfam library:
+
+``OpenFAM_INCLUDE_DIR``
+  where to find the openfam headers.
+``OpenFAM_LIBRARY``
+  where to find the openfam library.
+
+Hints
+^^^^^
+
+The environment variables ``OpenFAM_ROOT``, ``OpenFAM_DIR``, and ``OpenFAM_PATH``
+may also be set to help find openfam library.
