# Set up the pi for Qt compilation. On Arch I just install chromium which pulls in all the deps
# Removed xcomposite as code path breaks
# Remove 2 (mesa) pkgconfig files we allow screw our mkspec
# rm /usr/lib/pkgconfig/glesv2.pc
# rm /usr/lib/pkgconfig/egl.pc
# You are gonna want to export the following vars in /etc/profile.d

#export QT_QPA_PLATFORM=wayland
#export QT_WAYLAND_CLIENT_BUFFER_INTEGRATION=brcm
# Mount/copy this prepped rasp rootfs somewhere and set this path as the sysroot below
