Please, avoid following the suggestions blindly. This work needs a careful
check of what's exactly is being used and which header should provide the
necessary information. While it may compile it might be still wrong. You
need to (briefly) read the code in full. I don't use iwyu tool with tweaks
by Jonathan Cameron, old school guy, but you can also try it [1].
