@f3sch format header is not found when compiled for GPU, perhaps you would hide this include with #idef guards.

Indeed, I did now and test compiled on epn. I saw this in the past that hip libraries don't have <format> and I only tested cuda.

@davidrohr I saw this warning passing by but cannot understand how this is related to this PR, it doesn't seem unrelated though?
