Comment:
Cross compile is failing because QT_HOST_PATH isn't set (required when cross compiling with Qt 6 as it turns out).
Not sure how to make this work, the best information I found about this variable are two messages sent to a Debian mailing list by someone who also didn't seem to figure this out.
