Building Octave without QScintilla will disable the built-in code
editor, but the rest of the GUI and plot functions will be fully

It looks to me like the EPEL 7 repository has a qscintilla package built
against Qt 4, but not against Qt 5.

Is there a reason you want to build against Qt 5? I would recommend
building with Qt 5 when using an up-to-date distro like Debian or
Fedora, but using Qt 4 with a stable / enterprise / LTS distro like
CentOS 7 at this point. Maybe when CentOS 8 comes out it will have
better built-in support for Qt 5.
