In addition to the other suggestions about using a MSVC command prompt (which
work just fine for manual builds), Here’s what I’ve done when needing to
automate the build using powershell:
Invoke-BatchFile "${env:ProgramFiles(x86)}\\Microsoft Visual
Studio\\2017\\Community\\VC\\Auxiliary\\Build\\vcvarsall.bat" x86_amd64
Get-ChildItem env:* | Sort-Object name
…which invokes the vcvarsall batch and imports all of the environment vars that
were set by that invocation. vcvarsall is provided exactly for the purpose of
setting your env for building and it supports a few different arch arguments to
select the right toolchain.
HTH,
Mike
