If you want to avoid using the vcredist then you will need to build ALL your
projects and dependencies with the EXACT same version of Visual Studio. This
includes Qt itself.

 Some, including myself, take this route as we do not want to deal with the
vcredist headache. There are ramifications to doing this and you should
review those and understand what you are losing with this approach.
