The bug report is the answer. You can prepare the patches and even submit 
them, but they will not be accepted.

Qt 5.6 is ending its LTS lifetime. 5.9 has another year left, which means it 
does not need OpenSSL 1.1 support. According to 
OpensSL 1.0 will be supported and keep on receiving security fixes until 
2019-12-31, at which time Qt 5.9 will be over two and a half years old.

If you're choosing to stay with an LTS Qt, you should choose to stay with an 
LTS OpenSSL. If you want to upgrade other components across major versions, 
you should upgrade Qt too.

The next Qt LTS (5.12) has support for OpenSSL 1.1.
