+:: For VS2017, multiple instances can be installed on the same box SxS and VS150COMNTOOLS
+:: is no longer set as a global environment variable and is instead only set if the user

+::
+:: Following this logic, we will default to the VS2017 toolset if VS150COMNTOOLS tools is
+:: set, as this indicates the user is running from the VS2017 Developer Command Prompt and
+:: is already configured to use that toolset. Otherwise, we will fallback to using the VS2015
+:: toolset if it is installed. Finally, we will fail the script if no supported VS instance
