Server executables looking for wrong version of OpenSSL dll files

I've built and compiled in Windows and have OpenSSL 3.0 installed, when trying to run authserver.exe or worldserver.exe, I'm presented with the following errors:

worldserver.exe - System Error

The code execution cannot proceed because libcrypto-1_1-x64.dll was not found. Reinstalling the program may fix this problem.

OK

worldserver.exe - System Error

The code execution cannot proceed because libssl-1_1-x64.dll was not found. Reinstalling the program may fix this problem.

OK

Have I done something with the installation here? I'm not sure why it's looking for an older version of OpenSSL.

You need OpenSSL version 1.0.x as the official software requirements page states.
