<arch>: x86 | amd64 | arm | x86_amd64 | x86_arm | amd64_x86 | amd64_arm
--winstore Use Windows Store (rather than desktop) development tools
--sdkversion:<v> Use a specific Windows SDK version:
<v> is either the full Windows 10 SDK version number or
"8.1" to use the windows 8.1 SDK
Other command line arguments are passed on to the
Microsoft C/C++ compiler for the specified SDK toolset
