During vcpkg process if some file path exceed 260 characters, the vcpk build fail.
I happened on the duckdb-gcs extension see here for analysis and more details.
That looks like a known limitation on windows and maybe depend of the toolchain tools...

Long Path is already enabled on windows runner but seems not sufficient to prevent the issue with vcpkg ...
