ric Oh, sorry, the windows zip file is already compiled. The source is in the .tar.gz archive listed under "Linux/MacOS" --- it should work on Windows even though it says it is only for linux and mac. For example, the README.md in ouster_viz provides instructions for installing the dependencies on Windows.
Using Windows: install Visual Studio and vcpkg and then vcpkg install glfw3 glew tclap jsoncpp eigen3
Then, you can search online or contact Ouster support for how to compile cmake projects with Visual Studio. Compiling ouster_viz will automatically also compile the ouster_client library. Good luck!
