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 the octave library
``Octave::Octinterp``
include directories and the octinterp library including the dependency on
Octave::Octave
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
