Sure, it is possible.

If you're using a system Qt, it stands to reason that the system Qt has all 
its necessary dependencies installed. So this would not be causing you 
trouble. Therefore, I conclude you're not using a system-wide Qt.

You must be using a Qt deployed alongside your application. You can then just 
modify qsslsocket_openssl_symbols.cpp to search for your deployed libssl.so.1 
and libcrypto.so.1.
