Vendors libgpiod's C library sources via LIBGPIOD_VERSION (upstream's own setup.py fetch_tarball mechanism), so no system libgpiod is needed. The real test suite needs a gpio-sim kernel module and a separately-built libgpiosim helper library, neither available in the build container, so CI exercises the compiled extension and the real chip-open error path instead, matching upstream's own release process which does not run tests either.
Alpine needs linux-headers for lib/uapi/gpio.h's system linux/*.h includes; manylinux already has them via glibc-devel.

Without it cibuildwheel defaulted to aarch64/x86_64 and matched zero build identifiers against the cp*-*linux_riscv64 CIBW_BUILD selector.
Building wheels directly from a checkout meant setup.py's fetch_tarball decorator took the full-fetch path during build_ext, which deletes LICENSE/ lib/include right after compiling -- breaking install_egg_info's license copy. Upstream's own generate_pypi_artifacts.sh sidesteps this by building the sdist with LIBGPIOD_VERSION set first, then feeding that sdist (already carrying libgpiod-version.txt) to cibuildwheel, which takes the skip-fetch, no-cleanup path instead.

Not rehearsed locally -
lib/uapi/gpio.hneeds the real Linuxlinux/*.hheaders; validating directly on the riscv64 CI runners.
