Why does Octave build not see Qscintilla or jni.h?

I keep getting these errors upon setting up octave.

configure: WARNING: QScintilla library not found; disabling built-in Qt GUI editor
configure: WARNING: Include file <jni.h> not found.  Octave will not be able to call Java methods.
configure: 
configure: NOTE: Libraries or auxiliary programs may be skipped if they are
configure: NOTE: not found OR if they are missing required features on your
configure: NOTE: system.

I keep getting these errors when I try to run configure while installing octave. I don't know how to fix these and I've even ran

CPPFLAGS=-I/usr/lib/jvm/java-8-openjdk-amd64/include ./configure

to no avail. How can I get octave to find QScintilla library and jni.h? I even installed libqscintilla2-dev. This is Ubuntu 16.04 btw.

This may be the case where octave is trying to use Qt5 over Qt4.

If so, try running the command:

sudo apt install libqt5scintilla2-dev

This solved my problem with Qtscintilla.
