Boost is required for the raspberrypi IPA, so it's optional if you don't
need the raspberrypi pipeline. There was some discussion in separating
the two, such that you could compile the pipeline without the IPA if
boost isn't available, but we haven't progressed much with it yet.

You can configure which pipelines to build like so, enabling only the
raspberrypi and vimc pipeline handlers, for example:

meson -Dpipelines=raspberrypi,vimc build

You can do `meson configure` to list the options. Right now the
pipelines that we have are ipu3, raspberrypi, rkisp1, simple, uvcvideo,
vimc.
