# Try to find the build flags to compile octave shared objects (oct and mex files)
# Once done this will define
#
# OCTAVE_FOUND - if Coin3d is found
# OCTAVE_CXXFLAGS - extra flags
# OCTAVE_INCLUDE_DIRS - include directories
# OCTAVE_LINK_DIRS - link directories
# OCTAVE_LIBRARY_RELEASE - the relase version
# OCTAVE_LIBRARY_DEBUG - the debug version
# OCTAVE_LIBRARY - a default library, with priority debug.
