Usage:

|
Options:
|

/vcvars:platform:<arch> Specify the Compiler Platform Tools architecture
|
|
<arch>: x86 | amd64 | arm | x86_amd64 | x86_arm | amd64_x86 | amd64_arm
|
|
/vcvars:store Use Windows Store (rather than desktop) development tools
|
|
/vcvars:sdk:<version> Use a specific Windows SDK version:
|
|
<version> is either the full Windows 10 SDK version number or
|
|
"8.1" to use the windows 8.1 SDK
