Usage:
vccexe [options] [compileroptions]
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

--sdkversion:<v> Use a specific Windows SDK version:
<v> is either the full Windows 10 SDK version number or
