CFFI binding to libheif; none of libheif/libde265/libaom/x265 are packaged for riscv64 (Rocky 10 has neither in its base repos nor CRB), so the workflow builds all four from source exactly as upstream's own Dockerfile does, staging their licence texts alongside pyheif's own.

x265 3.6 (upstream's pin) hard-sets both policies to OLD; CMake 4 on the manylinux_2_39_riscv64 image errors outright regardless of CMAKE_POLICY_VERSION_MINIMUM, since it's an explicit cmake_policy() call rather than a bare cmake_minimum_required floor. 4.2 dropped both -- the same version pillow-heif's own riscv64 port already uses for this reason.
test_versions.py::test_pyheif_version reads pyheif/data/version.txt by a cwd-relative path instead of through the installed package; only tests/ was staged, so pytest ran from an empty dir missing that one file. The other 389 tests (real HEIC/HIF/AVIF decode against the installed wheel) already passed against the native build.

License: Wheel bundles x265 (GPL-2.0), libde265/libheif (LGPL-3.0), and libaom (BSD-2-Clause + patent grant) built from source; upstream ships no licence text for any of them, so the build adds it.
