Qt statically linked application error: linuxfb plugin not found by the application

I have successfully developed a graphical Qt 5.15.2 application using Qt Creator with dynamically linked libraries. For various reasons I have determined static linking would be better for my application. I attempted to switch my development environment to use static libraries instead of dynamic. My application built with no errors, but when I deployed my application to a development board (a BeagleBone Black running Debian 11.5), I got the following error:

qt.qpa.plugin: Could not find the Qt platform plugin "linuxfb" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

I passed in a -platform linuxfb command line argument, I built my own static Qt libraries, I added CONFIG += static to my .pro file, and I am using the static libraries in Qt Creator. Is there something special I need to do to get the linuxfb library/plugin to link? Any insight into how I can resolve this would be greatly appreciated.
