Worked on improving cross-platform library linking in the bazelbuild/rules_cc repository, focusing on compatibility with Windows SDK libraries. Addressed a bug in the build system by implementing case-insensitive matching for library filename extensions within the create_library_to_link function. This change allowed the build process to correctly recognize and link libraries with mixed-case extensions, such as .Lib and .LIB, which are common in real-world SDKs. Utilized Python for string handling and integrated the fix through Copybara, ensuring smoother library management and reducing build failures on Windows. The update enhanced the reliability and usability of Bazel’s C++ rules across platforms.
