I was able to build Slicer following [this tutorial](https://slicer.readthedocs.io/en/latest/developer_guide/build_instructions/windows.html)

I have not tested if all the functionalities work without crash but at least the sliceViews and the 3D View work.

I had to change one line of the instructions a little bit for it to work. Here it is in case some one needs it:

```auto
"C:\Program Files\CMake\bin\cmake.exe" -G "Visual Studio 16 2019" -A x64 -DQt5_DIR:PATH=C:\Qt\5.15.2\msvc2019_64\lib\cmake\Qt5 C:\D\S4\Slicer

```

You are correct that the “Visual Studio 16 2019 Win64” is not an appropriate generator name.  
See [CMake 3.14 Release Notes](https://cmake.org/cmake/help/latest/release/3.14.html#generators) where the CMake generator platform must be set with the “-A” command line option starting with the VS 2019 generator which was introduced in this version.

@mau_igna_06 That documentation can be changed in the following file which is located in the Slicer GitHub repo. Could you issue a PR to fix this? Thanks!
