Add Meson package (mesonbuild/wrapdb)

[gistrec]

The library is already available via vcpkg (port geo-utils-cpp), Conan (#17), build2/cppget (#18), and xrepo (#19).
This issue tracks publishing the library to Meson WrapDB to cover the Meson ecosystem.

Status

• Add Meson packaging files (geo-utils-cpp.wrap + packagefiles/.../meson.build with declare_dependency + override_dependency, upstream examples/gps_track.cpp registered as a smoke test) + releases.json entry (1.2.0-1)
• tools/sanity_checks.py passes locally (macOS arm64, AppleClang 17)
• Open PR to mesonbuild/wrapdb → Add geo-utils-cpp 1.2.2 mesonbuild/wrapdb#2820
• PR merged
• Update README with Meson/WrapDB installation instructions

CI status

22/24 sanity-check jobs are green — MSVC cl (x86/x64/arm64), MSYS2 (UCRT64/CLANG64/CLANGARM64), macOS (arm64/x86_64), Ubuntu (x86_64/aarch64/ppc64le/s390x), and Alpine (×7). The two clang-cl jobs (x64, arm64) are red on an upstream Meson bug, not the port:

File ".../mesonbuild/compilers/cpp.py", line 823, in _get_options_impl
File ".../mesonbuild/options.py", line 599, in set_versions
    assert all(std in self.all_stds for std in versions)

Meson 1.12.0rc1 (published 2026-07-07, picked up by wrapdb's --pre CI ~2h before our run) has ClangClCPPCompiler advertising vc++23, which is missing from ALL_STDS — so UserStdOption.set_versions() asserts during clang-cl C++ compiler detection for any C++ project (cl is unaffected). We were just the first cpp-wrap to hit it.

• Upstream fix: compilers/cpp: add vc++23 to ALL_STDS (fix clang-cl AssertionError) mesonbuild/meson#15986 (one line — add vc++23 to ALL_STDS)
• Do not work around it in the wrap. Wait for the fix to reach --pre, then re-trigger CI. Explanatory comment left on wrapdb#2820.
