# crossWinFull.sh -- cross-build the FULL calog CLI as a Windows PE (x86_64-windows-gnu) with zig.
#
# Prereqs under build/cross/win/ (pinned, NOT rebuilt here): openssl (libssl/libcrypto), libxml2,
#   pcre2, libssh2, mariadb, postgres (libpq+pgcommon+pgport), tcl (libtcl90), mruby (libmruby),
#   libarchive+codecs (xz/zstd/lz4/bz2/z), libwinpthreads. Rebuild them reproducibly from vendor/
#   source with `./tools/crossDeps.sh win` before running this script -- that is what makes the full
#   cross build reproducible from a clean checkout.
# Compilers: zcc-win / zcxx-win = `zig cc|c++ -target x86_64-windows-gnu`; zar = `zig ar`.
