Hi @AoGao-Kedoka thanks for your report.
I see that you are using Conan 2. I've filled a request to also update the offending line in #16678 (review). As this is a ConanCenterIndex issue I'll move the issue to that repo to track it there :)

It's also fixed for weeks in #15193

Ooops, you're right! There're so many opencv recipes it's sometimes hard to keep track of them
