That looks like it won't be very hard:

qtbase/src/network/ssl/qsslsocket_openssl_symbols.cpp, function libraryPathList():

1- scans any paths given in DYLD_LIBRARY_PATH
2- scans any paths under .app/Contents/Frameworks
3- scans a list of known system paths, starting with /lib, /usr/lib, /usr/local/lib

Inserting $prefix/lib between 2 and 3 above should ensure that the proper libssl and libcrypto are loaded. Given that this is well hidden internally I *think* there shouldn't be any ABI implications for QtNetwork dependents, but I'm rebuilding now to verify.
