Qt Versioning

Choose a Qt version that is consistent with the version of VisualStudio you downloaded earlier. Another consideration is the framework you wish to build BCI2000 with. For example, in this tutorial, we are compiling for the 2019 Visual Studio on a 64 bit system, make sure you select MSVC 2019 64-bit, which is demonstrated in the photo below. If you're using Visual Studio 2017 find the latest version of Qt that supports Visual Studio 2017 for whatever architecture you want to build BCI2000 on and install that version of Qt. Note that VisualStudio 2017 is binary compatible with VisualStudio 2015, so you may use the MSVC2015 32-bit package for a 32bit build using VisualStudio 2017.
