which opencv version to use?

I am currently using opencv version 4.5.4 to compile this project. It turns out giving me these errors:

What to do to solve these issues? Thanks!!

Hi there!
I've have just kept to the latest one, but I can see that I've commented out the OpenCV installation through pmm so the linking might bug out on Windows.
If you remove the comment on OpenCV in CMakeLists.txt#L88 that might solve this issue.

If this does not help, I suppose the linking is not working properly on windows..

It should also be noted that I have not gotten the time to ensure that this compiles on Windows as I currently only have Linux environments, but I hope to be able to do a roundup on adding Windows (and IOS) support later next year (sorry!).

I already remove the comment on OpenCV in CMakeLists.txt#L88, but still cannot solve this issue. I am compiling on windows 10.

Anymore advice, thanks!!
