Please help, How to build rpcs3 with visual studio 2017

Hi, I have many issues to rebuilt a specific commit of rpcs3, I follow the instructions of read me but i have troubles with qt, I can't understand this part:

Configuring Qt
If you're using Visual Studio 2017 without Qt plugin support (or simply dont want to use it):

1. Add
   QTDIR
2. environment variable and set it to
   <QtInstallFolder>\5.8\msvc2015_64\
3. OR
   open the SLN, wait for projects to load, in explorer open
   rpcs3qt/rpcs3qt.vcxproj.user
4. and set
   <QTDIR>QtInstallFolder/5.8/msvc2015_64</QTDIR>

If you wish to use the Visual Studio plugin for Qt:

1. Go to the Qt5 menu and edit Qt5 options. Add the path to your Qt installation with compiler e.g.
   C:\Qt\5.8\msvc2015_64
2. .
   
3. While selecting the rpcs3qt project, go to Qt5->Project Setting and select the version you added.
   

The commit what i want to build is this: 0da9c8d20, the version of visual studio is 2017 community, the version of windows is win 10 anniversary, Sorry for my english. Thanks.
