Normally mkoctfile sets the necessary -I flags to avoid this error
(both -I.../octave-<version> and -I.../octave-<version>/octave). Looks
like an issue with your Octave installation. You could call

'/path/to/the/right/mkoctfile -v -c dummy-file-name.cc'

to see the -I flags of its compilation command, maybe this helps to
figure out what is amiss.
