What is the location of file:
VCVARSALL.BAT
for Visual studio 2017?
Hans Passant is right.
I had the same problem: no VCVARSALL.BAT for my VS2017 and no Build folder in Microsoft Visual Studio\2017\Community\VC\Auxiliary.
I have Visual Studio Community 2015 and 2017 installed on the same machine.
I didn't have Desktop development with C++ check in my installation. I installed it and the Build folder was created!
Now everything work great.
