No source files found in compile args

[kuntryn]

got this error when compiling abseil library.

 in _get_files
    assert source_file_candidates, f"No source files found in compile args: {compile_action.arguments}.\nPlease file an issue with this information!"

This command seems try to generate a preprocessed header file, so it contains no cpp source files.

I see the same issue. I think this got broken with the Bazel update:

Made a lazy and likely wrong fix, but being in a hurry. Can be used by adding this to MODULE.bazel:

git_override(
    module_name = "hedron_compile_commands",
    remote = "https://github.com/eugeneo/bazel-compile-commands-extractor.git",
    commit = "844279a911d0a0adca480b299799f03f65290cce",
)

Would appreciate any suggestions on how to fix this properly.
