+FindOctave
+----------
+
+Finds GNU Octave interpreter, libraries and compilers.
+
+Imported targets
+^^^^^^^^^^^^^^^^
+
+This module defines the following :prop_tgt:`IMPORTED` targets:
+
+``Octave::Interpreter``
+  Octave interpreter (the main program)
+``Octave::Octave``
+  include directories and libraries
+
+If no ``COMPONENTS`` are specified, ``Interpreter`` is assumed.
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+``Octave_FOUND``
+  Octave interpreter and/or libraries were found
+``Octave_<component>_FOUND``
+  Octave <component> specified was found
+
+``Octave_EXECUTABLE``
+  Octave interpreter
+``Octave_INCLUDE_DIRS``
+  include path for mex.h
+``Octave_LIBRARIES``
+  octinterp, octave libraries
+
+
+Cache variables
+^^^^^^^^^^^^^^^
+
+The following cache variables may also be set:
+
+``Octave_INTERP_LIBRARY``
+  path to the library octinterp
+``Octave_OCTAVE_LIBRARY``
+  path to the liboctave library
