FYI @mattalvarado: I think this combination of changes should fix all of the current CI failures. So I would treat #315, #316, #317, #318, and #320 all as valid/functional changes assuming you agree with them otherwise.

In general, seems like these CI failures fell into a few categories:

• Dependency version bump (OpenCV bumped to >=5) caused CMake configuration failure.
• Compiler version bump (macOS Homebrew-installed LLVM bump to C++23) exposed transitive dependencies that we were relying on.

In either case, these issues were only discovered because the CI does not pin these dependencies and compiler standards. But at the same time the CI began failing as a result of the silent version bumps. Not sure if you have any opinions on whether these things should be fixed rigidly or if you prefer using the latest-and-greatest even if silent CI failures will crop up.
