I’ve tested latest Slicer master branch build using VS2017 and VS2019:

- Slicer build and self-tests were successful (the same tests fail as in the nightly with VS2015)
- Installation of scipy, matplotlib, and wxPython was successful (pip\_install script did , and everything seemed to work fine (tested the plotting features with scripts [here](https://discourse.slicer.org/t/use-full-power-of-python-in-slicer/7162/5)).
- Packaging succeeded.

There is just one set of warnings on VS2017 that might cause issues on systems that don’t have VS2017 runtime libraries installed: “_CMake Warning at C:/Program Files/CMake/share/cmake-3.14/Modules/InstallRequiredSystemLibraries.cmake:558 (message): system runtime library file does not exist: ‘MSVC\_REDIST\_DIR-NOTFOUND/x64/Microsoft.VC141.CRT/msvcp140.dll’_” - but this seems to be a CMake issue and we can address it if we switch to VS2017 or VS2019 for the official builds.
