Cython/pybind11 wrapper around Google's RE2 regex engine. Upstream ships manylinux x86_64/aarch64 wheels via EPEL's re2-devel, which isn't available on riscv64 (gotcha 51); abseil-cpp and re2 are built from source instead, reusing the recipe the already-published google-re2 build proved on this image.

No riscv64 wheel exists for the pinned cmake version, so
CIBW_BEFORE_BUILD's pip install builds it from source as a build
dependency. That build runs CMake's own bootstrap CMakeLists, whose
Utilities/cmcurl/CMakeLists.txt calls find_package(OpenSSL); the
manylinux_riscv64 image ships openssl-libs but no -devel headers, so
all 4 build legs failed identically with:
CMake Error at Utilities/cmcurl/CMakeLists.txt:772 (message):
Could not find OpenSSL.
Install openssl-devel in CIBW_BEFORE_ALL before cmake gets pip
installed, same fix as build-executorch.yml.

Patches
0001-pyproject-widen-license-files-to-cover-re2-and-abseil.patch- Inappropriate (riscv64-only build detail). Without it the two added LICENSE files are dropped by the exact-listlicense-files.No local build check: no CMake/C++ toolchain in this sandbox to compile abseil-cpp/re2 or run cibuildwheel; the abseil+re2 from-source recipe itself is reused verbatim from the already-published google-re2 build.
