:: 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
:: can be found.
