This one is actually optional - it's just a sub-optimal method to work
around it.

I'd really like this to be automatic so that if it's not found the
raspberry-pi pipeline is disabled, and I even have a patch I created
several weeks ago.

But I'm not particularly happy with that - and so I haven't submitted it ;-(

I think we could add this as [optional], stating that it is required to
enable the RPi IPA.

The difficulty is that the RPi IPA is enabled by default, so that's why
it impacts users more.

To disable, you can specify -Dpipelines=vimc,uvcvideo,ipu3,rkisp1 on the
meson configuration line.

That's not particularly friendly either though - so maybe I should just
post my patch to disable the RPi IPA when there is no boost library
found, and hash it out on there.
