Bazel 7 breaks cmake rule

[shmuelamit]

Here's the setup to reproduce:
libevent.BUILD:

load("@rules_foreign_cc//foreign_cc:defs.bzl", "cmake")

filegroup(
    name = "srcs",
    srcs = glob(["**"]),
)

cmake(
    name = "libevent",
    lib_source = ":srcs",
    visibility = ["//visibility:public"],
    build_args = ["-j 128"]
)

WORKSPACE:

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")

http_archive(
        name = "libevent",
        build_file = "//:libevent.BUILD",
        sha256 = "92e6de1be9ec176428fd2367677e61ceffc2ee1cb119035037a27d346b0403bb",
        strip_prefix = "libevent-2.1.12-stable",
        url = "https://github.com/libevent/libevent/releases/download/release-2.1.12-stable/libevent-2.1.12-stable.tar.gz",
)

MODULE.bazel:

module(name = "test", version = "1.0.0")

bazel_dep(name = "rules_foreign_cc", version = "0.10.1")

Along with an empty build file, when building with Bazel 6.4.0 the rule works flawlessly, however when building with Bazel 7 it causes broken symlinks in header files:
