build-rpi3-qt.sh

#!/bin/bash

# The script does not handle exceptions so its your responsibility to handle
# them according to your situation. Simply;
# - Don't run the script before building RPI3 image
# - Run it once. Then, handle it manually if it is required
#
# It is more handy for me to handle my own Qt out of Buildroot but I may
# implement this as Buildroot package in future with a proper kconfig
# implementation.
