-- compat.hiredis — hiredis 1.2.0, minimal C client for Redis.
--
-- Shape A (C-source compat), same as compat.cjson / compat.zlib: the seven
-- .c files upstream's own CMake compiles into libhiredis, listed verbatim.
-- ssl.c (hiredis_ssl, needs OpenSSL) and test.c stay out.
--
-- INCLUDE LAYOUT. Upstream's INSTALL layout is `<includedir>/hiredis/hiredis.h`
-- and redis-plus-plus's sources spell `#include <hiredis/hiredis.h>`, but the
-- release tarball keeps every header FLAT at the root. mcpp include_dirs are
-- plain globs with no rename, so this package ships two thin wrapper headers
-- through generated_files that re-include the real flat headers with the
-- ANGLE-bracket form (which skips the wrapper's own directory):
--   mcpp_generated/include/hiredis/hiredis.h -> #include <hiredis.h>
--   mcpp_generated/include/hiredis/async.h   -> #include <async.h>
-- Same trick as compat.opengl's mcpp_generated/include/GL/gl.h and
-- compat.glx-headers' mcpp_generated/include/X11/Xpoll.h. The real headers'
-- internal `#include "read.h"` etc. are relative, so they resolve next to the
-- real file inside the wrap dir.
--
-- VERSION. 1.2.0 is the classic, widely-shipped release (Debian 12 / Ubuntu
-- 24.04 stable carry 1.2.0; it was vcpkg's long-standing default). Every
-- hiredis 1.x release shares this exact source list and layout, so adding
-- 1.3.x/1.4.x later is just one more xpm row — the mcpp block never changes.
--
-- No CN mirror yet: `url` is a plain string (upstream GitHub release only),
-- the documented fallback when there is no mcpp-res write access
-- (docs/cn-mirror.md; precedent: compat.spdlog).
