How to generate a windows-target package (zip file) from source code

I’m working on Windows OS and try to build Grafana windows version. The build task in Makefile works fine, and I saw the build result grafana-server.exe was generated under bin folder.
While I have no idea how to package them to a zip package, like what we can download from official:
There’s no such a command in Makefile. Except grafana-server.exe & grafana-cli.exe, there’re many other files need to be included to the package, but I can’t find a docuement to tell me how to do this, which files should be included.

Can you help me? How grafana team did the windows packing in each release?

Best Regards
