Oh! I hadn't thought of that.

On Windows, it shouldn't be a problem since people need to install OpenSSL 
manually, so they'll naturally get 1.1. On Mac, we haven't used OpenSSL for a 
few releases. The problem is the current crop of Linux stable distributions.

We already build with C++17, but with GCC 5.

But I say people who need OpenSSL 1.0 should stay with 5.10, one of the LTS, 
build from sources, or use their distribution's packages. There are a lot of 

UNLESS this will make the Qt SDK installer and maintenance tool not work.
