requirements accordingly.

Is this fixing some specific autobuilder failure ? If so, do you have a
reference ?

Thanks!

No, that's a pre-requisite for patch 3/3.

libcamera is now built with C++17 as a minimum requirement.

In this case, we'll squash 2/3 and 3/3 together.

Thanks!

So the C++17 requirement comes with the version bump. In this case, it
should be a single patch: bump and add new requirements.

Otherwise, if we end up not applying, or reverting patch 3, then C++17
requirement is superfluous on its own.

Yann E. MORIN.
