gn's build/gen.py links with -static-libstdc++, and the riscv64 manylinux image ships no libstdc++.a (gotcha 77), so the first run died at `LINK gn` with `cannot find -lstdc++`. build-skia-python.yml installs the same package before bootstrapping gn.

skia-pathops0.9.2Compiles a Cython extension statically linked against a slimmed-down Skia (no GPU, codecs or fonts). Upstream publishes no riscv64 wheel.
Mirrors upstream's
ci.ymland, for libskia, skia-builder'sci.yml.Differs from upstream
build_skia.py- skia-builder releases no riscv64 libskia.fetch-gnrevision - CIPD has no riscv64 gn.Matrix: one
cp310-abi3wheel, built on cp310 and tested on cp310-cp314, like upstream.Testing
License: Wheel statically links Skia (BSD-3-Clause), whose licence upstream does not ship, so the build adds it.
Patches
0001-package-the-licence-of-the-statically-linked-Skia.patch- To upstream. Without it the wheel omits Skia's licence. Not riscv64-specific.
