Before that you might want to check that your Qt doesn't already support fbdev.
eg.
$ kcalc -platform help
This application failed to start because it could not find or load the
Qt platform plugin "help"
in "".

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl,
offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl,
wayland-xcomposite-glx, xcb.

$ kcalc -platform linuxfb
