Code Review

This pull request is an automated update for the fbgemm package to version v1.4.2. The change correctly adds the new version to the xmake.lua package file. My review identifies a potential maintainability issue related to a broadly scoped patch that will be applied to this new version. While the change itself is simple, this associated risk should be considered to ensure future build stability.

[gemini-code-assist]

While adding this new version is correct, it falls under the wide-ranged patch rule >=1.1.0 on line 16. This is a maintenance risk, as the patch might not be compatible with v1.4.2 since the CMakeLists.txt file it modifies could have changed. For better long-term maintenance and to avoid unexpected build failures, it's recommended to use more specific version constraints for patches. For example, the existing patch could be constrained to older versions (e.g., >=1.1.0, <=1.2.0), and a new, verified patch configuration could be added for v1.4.2 if it's still needed.
