Retarget to higher visual studio version in Cmake Project

I got into this problem when I was trying to compile VK-GL-CTS on my new windows machine but I have installed the latest version of Visual Studio which was `Visual studio 2019`

Now when I tried to compile it as per the steps in VK-GL-CTS I get the weird issue.

CMake Error at CMakeLists.txt:16 (project):
  Failed to run MSBuild command:
    MSBuild.exe
  to get the value of VCTargetsPath:
    Microsoft (R) Build Engine version 16.5.0+d4cbfca49 for .NET Framework
    Copyright (C) Microsoft Corporation. All rights reserved.
    Build started 5/12/2020 7:19:51 PM.
    ...

    ...
    Build FAILED.

So the problem is pretty weird and not quite understandable at least for me. (I am not a windows guy)

Then i tried to look into the Generators.

cmake .. -DDEQP_TARGET=default -G

CMake Error: No generator specified for -G

So the problem is pretty much clear that there is no Visual Studio 2019 here, Hence we need to Retarget our solution. 

but ..

We have no solution generated yet

Solution

Hence we can use 

cmake .. -DDEQP_TARGET=default -G"Visual Studio 15 2017 Win64" -T v142,host=x64

This will make use of v142 toolset which is our Visual studio 2019 toolset.

You can find the version when you go in the directory as below.

C:/Program Files (x86)/Microsoft Visual Studio/2019/Enterprise/VC/Tools/MSVC/14.25.28610

Now it happily built and i am able to get the solution (.sln file) :)
