-You also need to have Gwyddion open source software installed to provide output to .gwy files.

 Under Windows environment we use MS Visual Studio 2015, and we can provide a solution and project files together with all the necessary dependencies upon request. This MSVC version is able to compile 64-bit binaries, and indeed we succeded to complete the build. However, the 64-bit XSvit binary behaves oddly so we decided not to publish GSvit-x64 for now. We plan to put these together with all dependencies in the svn repository. ​ Under Windows environment we use MS Visual Studio 2015, and we can provide a solution and project files together with all the necessary dependencies upon request.
