-:: Default to highest Visual Studio version available
-::
-:: For VS2015 (and prior), only a single instance is allowed to be installed on a box
-:: and VS140COMNTOOLS is set as a global environment variable by the installer. This
-:: allows users to locate where the instance of VS2015 is installed.
-::
-:: 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
-:: has launched the VS2017 Developer Command Prompt.
-::
-:: 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
