Subject: [PATCH] [build.zig] Fix Zig emscripten build (#4012)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Fix for issue #4010

Split the code for Zig's master branch and >= 0.12.0 due to changes in https://github.com/ziglang/zig/pull/19623

* Restore the cache_include path which was removed in error

Accidently removed a couple lines I didn't mean to 🙈
