cmeel-qhull: Add version 8.0.2.1 - #2160

Conversation
qhull provides convex hull, Delaunay triangulation, Voronoi diagram and halfspace intersection, and cmeel-qhull is the cmake-wheel distribution the pinocchio/hpp-fcl robotics stack installs it from. No riscv64 wheel exists on PyPI, so the cmeel dependents cannot resolve on riscv64. [tool.cmeel] has-sitelib = false, so the wheel carries no Python extension and a single py3-none-manylinux_riscv64 wheel covers every interpreter; build-number = 1 makes v8.0.2.1.c1 the tag that reproduces the current release. qhull's CMakeLists.txt declares cmake_minimum_required(VERSION 3.0) while cmeel[build] resolves CMake >= 4, which refuses anything below 3.5; CMAKE_POLICY_VERSION_MINIMUM=3.5 in CIBW_ENVIRONMENT fixes it without a patch.

…7-508 Gotcha 507: a segfault out of a hand-written ctypes smoke test is usually the test's own declaration - c_char_p.in_dll on a C char array dereferences the string's first bytes as a pointer, and a call with no restype/argtypes returns garbage. Reproduce the line against the local x86 build before blaming riscv64. Gotcha 508: a job is not hung because the agent's own sense of elapsed time says so - an agent session's sleep does not track the runners' clock. Compare the job's started_at with date -u, let timeout-minutes do the killing, and re-run a run rather than cancel it.

cmeel-qhull8.0.2.1Builds qhull 8.0.2 - the
libqhull_rshared library, the staticlibqhullcpp/libqhullstaticarchives, headers, CMake/pkg-config files and the qconvex/qdelaunay/qvoronoi/qhalf/rbox tools - into a cmeel prefix through thecmeelCMake build backend, for the robotics stack that consumes convex hulls from it. Upstream publishes no riscv64 wheel.Mirrors upstream's
release.yml.Differs from upstream
CMAKE_POLICY_VERSION_MINIMUM=3.5- qhull still declares a CMake 3.0 minimum, which CMake 4 rejects.Matrix: one job -
[tool.cmeel] has-sitelib = false, so the singlepy3-none-manylinux_riscv64wheel covers every interpreter.Testing
libqhull_r.sothroughctypesand hulls/triangulates generated point sets with the wheel's own tools.License: Wheel ships qhull under the Qhull licence, with upstream's
COPYING.txtincluded as it is on every other arch.Builds clean from the tag with no patches; a QEMU riscv64 rehearsal produced a wheel whose namelist matches upstream's x86_64 release wheel exactly.
