# - Find Octave
# GNU Octave is a high-level interpreted language, primarily intended for numerical computations.
# available at http://www.gnu.org/software/octave/
#
# This module defines:
# OCTAVE_EXECUTABLE - octave interpreter
# OCTAVE_INCLUDE_DIRS - include path for mex.h, mexproto.h
# OCTAVE_LIBRARIES - required libraries: octinterp, octave, cruft
# OCTAVE_OCTINTERP_LIBRARY - path to the library octinterp
# OCTAVE_OCTAVE_LIBRARY - path to the library octave
# OCTAVE_VERSION_STRING - octave version string
# OCTAVE_MAJOR_VERSION - major version
# OCTAVE_MINOR_VERSION - minor version
# OCTAVE_PATCH_VERSION - patch version
# OCTAVE_OCT_FILE_DIR - object files that will be dynamically loaded
# OCTAVE_OCT_LIB_DIR - oct libraries
# OCTAVE_ROOT_DIR - octave prefix
#
# The macro octave_add_oct allows to create compiled modules.
# octave_add_oct ( target_name
# [SOURCES] source1 [source2 ...]
# [LINK_LIBRARIES lib1 [lib2 ...]]
# [EXTENSION ext]
# )
#
# To install it, you can the use the variable OCTAVE_OCT_FILE_DIR as follow:
# file ( RELATIVE_PATH PKG_OCTAVE_OCT_FILE_DIR ${OCTAVE_ROOT_DIR} ${OCTAVE_OCT_FILE_DIR} )
# install (
# TARGETS target_name
# DESTINATION ${PKG_OCTAVE_OCT_FILE_DIR}
# )
