--------------------+---------------------------
 I recommend OSGeo4W's Qt packages be updated to 5.12.4 or latest LTR
 version, specifically for this OpenSSL v1.1.1 reason:

 https://www.qt.io/blog/2019/06/17/qt-5-12-4-released-support-openssl-1-1-1

 I think it is a security concern to rely upon an OpenSSL version that is
 3+ years old, as is the case with official Qt < 5.12.4 releases. For one
 example, there is no TLS 1.3 support in OpenSSL 1.0.2.

 This 5.12.x LTR version may be the last available open-source binary
 distribution from Qt, so the package script looks like it can be updated,
 i.e. Qt doesn't need to be compiled yet.
