"Recently converted a VS2017 with Qt 5.13.1 project to use the latest Qt Vs Tools project settings, but I'm running into an issue with building.
Visual Studio detects a change every time on build rather than saying the project is up to date. I enabled diagnostic logging to identify the change, and it is related to this:
When I rename the qtvars designtime file that is already there to match what it's expecting, it's fine. But if I do a clean, it generates a new property file and I'm back in the same situation."
