:: This script initializes various Visual Studio related environment variables needed for building.
:: the dependencies. This batch file expects a CMake generator as %1. If %1 is not provided, it is
:: deduced from the VisualStudioVersion environment variable and from the location of cl.exe.
:: User-friendly VS generators are allowed (e.g. "vs2013-x86") and converted to the appropriate CMake ones.

:: NOTE This batch file expects the generator string to be CMake 3.0.0 and newer format, i.e.
:: "Visual Studio 10 2010" instead of "Visual Studio 10". However, one can use this batch file
:: also with CMake 2 as the generator will be converted into the older format if necessary.

:: NOTE: The delayed environment variable expansion needs to be enabled before calling this.
