Trouble compiling QZDoom

[Jaxxoon R]

Currently trying to compile QZDoom. I'm pretty sure I've downloaded and installed everything the wiki guide says to, but when I go to use CMake, it tells me:

Failed to run MSBuild command:

MSBuild.exe

to get the value of VCTargetsPath:

I did install Visual Studio 2017 instead of 2015 (since it seems like Microsoft tried its damnedest to make getting 2015 a pain). But at the time I figured it couldn't possibly hurt, right? Is this what's causing the issue? If it is, then does anyone know how I can get the correct version of Visual Studio? I'm still new to the whole compiling thing, I've only compiled GZDoom once and that was a couple of years back.

Does compiling GZDoom work?

At the moment GZDoom is more updated - it has QZDoom merged in and I try to keep the code in a useable state with the Travis CI notifications.

Please configure it to a new build directory and post whole output.
What's branch and commit you are using?

On a whim I tried setting it to configure for VS2017 instead of VS2015 and it seems to work fine CMake creates the build project and Visual Studio compiles it all without issue.

Seems there's been unintended consequences. For some reason all the executables I compile have really bad performance, even after setting the build type from "Debug" to "Release."
