Indeed, but it's only libcamera.so that other projects will link
against, and I don't "think" having LGPL has any effect on the build of
the documentation, or cam/qcam.
As the Android metadata library is just 'used' by libcamera.so, I don't
think it has much effect there?
Who knows. ... IANAL :-)
Do we need to hire a lawyer to tell us the right answer? Or perhaps ask
FSF or such an organisation?
