You don't need a full Visual Studio 2015 installation. You can install
Visual C++ 2015 Build Tools [1], which includes MSBuild, and use the
x86 or x64 native tools command prompt. Install the WDK to get the
Windows debuggers windbg, cdb, kd, and ntsd.

To build the external dependencies, you'll need svn and nasm in PATH.
You don't need git if you've downloaded the source manually. Ignore
the warning if it can't find git.
