Lightning Talk: Shimming OpenSSL Out of Necessity
summary
A prebuilt library expects removed symbols so linking fails with an undefined reference to SSL_library_init because that name became a macro in newer OpenSSL. The fix is to build a tiny CMake shim library that defines those names as real functions, reproducing a handful of legacy APIs. The claim is concrete: a binary built for OpenSSL pre‑1.1.1 can run against OpenSSL 3.x after adding OpenSSL 1.1.1 -> 3.x symbol shims; it works but is a pragmatic hack, not ideal.
