cmeel-octomap: Add version 1.10.0 - #2159
Merged

Conversation
Build the OctoMap 1.10.0 cmeel distribution for riscv64: liboctomap, liboctomath, their headers, CMake/pkg-config files and command-line tools, installed into the shared cmeel prefix. [tool.cmeel] has-sitelib = false, so the wheel holds no Python extension and one py3-none-manylinux_riscv64 wheel covers every interpreter; the build runs as a single cibuildwheel job. The tag's .c5 suffix is the cmeel packaging revision, which the backend stamps as the wheel's build tag. Mirrors upstream's release.yml, including CMEEL_RUN_TESTS=false: octomap's test_color_tree asserts a hardcoded node count that changes wherever the compiler contracts a*b+c into an FMA, which riscv64 does by default.

Gotcha 504: a test failing on riscv64 with a discrete wrong count, not a last-ULP value, can still be floating point - GCC's default -ffp-contract=fast fuses a*b+c into an FMA on rv64gc, which moves quantised coordinates into other buckets. octomap's test_color_tree gets 3431 nodes instead of 1034, and x86 reproduces it exactly under -march=haswell -ffp-contract=fast. Gotcha 505: a cmeel queue note's build number is not always 0, and one listing several means the same wheel version was packaged more than once - build the highest .cN tag rather than an assumed .c0.

cmeel-octomap1.10.0Builds OctoMap 1.10.0 - the octomap/octomath shared libraries, their headers, CMake/pkg-config files and command-line tools - into a cmeel prefix through the
cmeelCMake build backend. Upstream publishes no riscv64 wheel.Mirrors upstream's
release.yml.Differs from upstream
Matrix: one job -

CMEEL_RUN_TESTS=falseand only installs the wheel.log2graph/graph2tree.License: Wheel ships liboctomap/liboctomath, whose sources are BSD-3-Clause, under upstream's declared
BSD-3-Clauseexpression; no licence text ships, as in upstream's own wheels.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.
