PHP_ADD_EXTENSION_DEP doesn't fail when expected (build system)

Description

I have the following m4 code: https://github.com/pmmp/ext-pmmpthread/blob/6a516e5b58d326e2dcc23bb75fba6e210d5b313f/config.m4#L33-L44

        CLASSES_SRC="classes/pool.c classes/thread.c classes/thread_safe_array.c classes/thread_safe.c classes/runnable.c classes/worker.c"
        PHP_NEW_EXTENSION(pmmpthread, php_pmmpthread.c $CLASSES_SRC src/copy.c src/monitor.c src/worker.c src/globals.c src/prepare.c src/store.c src/handlers.c src/object.c src/routine.c src/queue.c src/ext_sockets_hacks.c, $ext_shared,, -DZEND_ENABLE_STATIC_TSRMLS_CACHE=1 -Werror=implicit-function-declaration)
        PHP_ADD_BUILD_DIR($ext_builddir/src, 1)
        PHP_ADD_INCLUDE($ext_builddir)

        if test "$PHP_PMMPTHREAD_SOCKETS" != "no"; then
                AC_MSG_NOTICE([Support for passing Socket objects between threads enabled. The sockets extension must be loaded at runtime. You can disable support using --without-pmmpthread-sockets.])
                AC_DEFINE(HAVE_PMMPTHREAD_EXT_SOCKETS_SUPPORT, 1, [Whether pmmpthread supports passing Socket objects between threads])
                PHP_ADD_EXTENSION_DEP(pmmpthread, sockets)
        else
                AC_MSG_NOTICE([Support for passing Socket objects between threads disabled. You can enable support using --with-pmmpthread-sockets.])
        fi
fi

When using --disable-all or --disable-sockets in conjunction with --with-pmmpthread-sockets, I expect the configure command to fail (because of the PHP_ADD_EXTENSION_DEP(pmmpthread, sockets)), but it doesn't.
The build proceeds and results in a compile error due to sockets being disabled.

Similar code for Windows works correctly.

PHP Version

PHP 8.2 git 6a914cb7a50fafbda38a4d8acce3a06b97dbd994

Operating System

WSL2 Ubuntu 20.04

Bắt đầu với ví dụ config.m4 được liên kết và lần theo PHP_ADD_EXTENSION_DEP(pmmpthread, sockets) qua các macro tạo configure. Tái hiện bằng --disable-all hoặc --disable-sockets cùng với --with-pmmpthread-sockets, sau đó so sánh đường dẫn Unix với hành vi trên Windows; hoàn tất khi configure từ chối dependency bị thiếu trước khi biên dịch.
