Examine the Tiled build system (likely CMake) and existing release scripts for Windows. The issue requests adding a portable zip/7z download to SourceForge. Review the current SourceForge download page for Tiled to understand the current binary distribution format. Investigate any existing build scripts or CI configurations that produce the installer, and consider how to generate a self contained portable archive. Look for comments in the issue thread that may discuss packaging tools like NSIS or 7zip.
