Björn Blissing 09eefd7973 Added script to identify Windows version
Added script to identify the Windows version used to compile the source.
Currently the windows version for Windows NT is hard coded into the
source. By running this CMake script the _WIN32_WINNT preprocessor
variable gets set to the corresponding windows version.
