Python Quickfix-SSL Error: OPENSSL_Uplink: no OPENSSL_Applink

Question

I am trying to use quickfix-ssl which exposes the SSLSocketInitiator/Acceptor capabilities currently unsupported in quickfix. Unfortunately there are no pre-compiled .whls for windows os so having to compile from source. I've had to modify "setup.py" as the current config was linux-oriented.

After solving several compiler link errors, I have managed to compile and install the resulting .whl. However, when I attempt to run the application, specifically, SSLSocketAcceptor() I get the error "OPENSSL_Uplink(00007FFAC47C2AC8,08): no OPENSSL_Applink".

In an attempt to solve the issue I followed this solution and added to the "UtilitySSL.cpp" source file and rebuilt but the issue persists, so now I am completely at a loss. Any help would be very much appreciated.

Python Version: 3.7 SSL Version: 1.1.1g OpenSSL Version (from VCPKG): 3.1.4.
