Do we need to add any licence information in here?, or in .reuse/dep5 at
all?

If this file was generated by meson, it could populate this field. But I
fear that's a bit 'chicken and egg'.

How does ROS handle sources? Does it include libcamera as a subproject?
or using the repo tool perhaps?

That's correct for the library itself, but not the utilities or other
toolings. And the IPA modules have different licence constraints.

Does a package.xml file have the ability to state multiple licences, or
specify what the license applies to?
