Doesn't ring a bell for me, but 2.1.9 is from late 2019, so maybe it's 
something that has long since been fixed?

https://github.com/microsoft/vcpkg/blob/master/ports/openimageio/vcpkg.json

Seems to indicate that the current vcpkg recipe for OIIO will build 2.3.10.1. 
That's not the very latest, but it's pretty close. So you ought to be able to 
build that with vcpkg easily and test a relatively up to date version.
