+Subject: Fix ONNX build warnings and remove std::filesystem dependency.
+
+Extracted from cmake/patches/onnx/onnx.patch in onnxruntime PR #24012
+<https://github.com/microsoft/onnxruntime/pull/24012> (commit
+23f764490838c0855798471fb93ec3aadd723e18).  The ONNX_MINIMAL_BUILD
+parts were removed as they are not needed for the Guix package.
