Build Fails: Project File Missing

So I'm following the Windows install instructions for OpenCV 3 and Visual Studio 2015 and everything goes fine until I get to the cmake command at which point I get the following error:

Selecting Windows SDK version 10.0.17763.0 to target Windows 10.0.17134.
CMake Error at CMakeLists.txt:3 (project):
Failed to run MSBuild command:

C:/Program Files (x86)/Microsoft Visual Studio/2017/Community/MSBuild/15.0/Bin/MSBuild.exe

to get the value of VCTargetsPath:

Microsoft (R) Build Engine version 15.9.21+g9802d43bc3 for .NET Framework

Copyright (C) Microsoft Corporation. All rights reserved.

MSBUILD : error MSB1009: Project file does not exist.

Switch: VCTargetsPath.vcxproj

Exit code: 1

Configuring incomplete, errors occurred!
