# Vendored third-party: zlib + minizip-ng (ZIP, C) and unrar 7.20.1 (RAR,
# C++). unrar sources are compiled as a static library in RARDLL mode (no
# main()); the project talks to it through the extern "C" DLL API in
# third_party/unrar7/unrar_c_api.h. Compiled with relaxed warnings (-w) —
# these are not our code and we do not want to chase upstream style updates.
#
# C++ compilers: PS5 uses prospero-clang++ (FreeBSD-style sysroot; the
# toolchain defaults to -stdlib=libc++, driver links libc++ automatically);
# host builds use the plain host C++ compiler (libstdc++).
