compat.rapidcsv.lua

-- Form B inline descriptor for rapidcsv, a CSV parser delivered as a single
-- header. Upstream's CMake target is INTERFACE-only and exposes `src/`, so a
-- small C anchor gives mcpp a buildable library target while consumers use
-- `#include <rapidcsv.h>`.
--
-- `include_dirs = {"*/src"}` is NOT `{"*"}`: the header lives in `src/` inside
-- the archive's `rapidcsv-<ver>/` wrap layer, and the leading `*` absorbs that
-- wrap layer. Pointing at the tarball root instead would still compile the
-- anchor below -- and would still build every consumer that never includes a
-- rapidcsv header -- while `<rapidcsv.h>` failed to resolve. That is why the
-- package is exercised by a consumer test holding a real assertion, not by
-- `mcpp build`.
--
-- There is nothing to gate: the library is one header, and a header-only
-- optional part cannot be hidden behind a feature (the include root is shared).
--
-- No CN mirror yet -- the url stays a plain string (the documented fallback
-- when there is no `mcpp-res` access). Adding the mirror later only rewrites
-- `url` into `{ GLOBAL = …, CN = … }`; the sha256 does not change.
--
-- Upstream targets C++11 and later, but this package is built by mcpp, whose
-- supported standard starts at C++20: the anchor uses C++23 and consumers
-- remain free to compile the header in whatever mode they choose.
