# - Try to find a version of Octave and headers/library required by the
# used compiler. It determines the right MEX-File extension and add
# a macro to help the build of MEX-functions.
#
# This module defines:
# OCTAVE_INCLUDE_DIR: include path for mex.h, mexproto.h
# OCTAVE_OCTINTERP_LIBRARY: path to the library octinterp
# OCTAVE_OCTAVE_LIBRARY: path to the library octave
# OCTAVE_CRUFT_LIBRARY: path to the library cruft
# OCTAVE_LIBRARIES: required libraries: octinterp, octave, cruft
# OCTAVE_CREATE_MEX: macro to build a MEX-file
#
# The macro OCTAVE_CREATE_MEX requires in this order:
# - function's name which will be called in Octave;
# - C/C++ source files;
# - third libraries required.
