It's (current year), please to be updating license headers to say 2025 instead of 2024.

@cstap14 please do exactly what you did (spectacularly) for SigFn, we need the license headers to say 2025. Please and thank you sir.

We have 5 million other problems for this library, but this issue is only for license business. Please ignore the absolute atrocity I created when attempting functions in CMake.
