To build without a CLI showing on Windows build with: go build -ldflags -H=windowsgui ..
To ensure we get proper configuration on each OS, we sometimes need extra files that are part of the compilation. This ensures we do get things like icons and proper DPI awareness (which is important for crisp text).
Those manifests are turned into files (e.g. *.syso) that get detected and used by go build automatically.
The Windows manifest and icon are placed inside the .winres folder, which gets compiled into the required
*.syso files by running go-winres make --in ./.winres/winres.json.
go-winres can be installed using go install github.com/tc-hib/go-winres@latest.
Note: Any changes to things in .winres requires re-running the go-winres command and then recompiling the Go program.
