Errors with validating TreeArtifact with Bazel 7

[mvukov]

I am trying to migrate my repo https://github.com/mvukov/rules_ros2 to Bazel 7. Basically any target that's using rules_foreign_cc fails. For instance:

bazel build @cyclonedds//:cyclonedds
INFO: Analyzed target @@cyclonedds//:cyclonedds (50 packages loaded, 9242 targets configured).
ERROR: /home/user/.cache/bazel/_bazel_user/97780932f72da4bf457551d43f4a7dc9/external/cyclonedds/BUILD.bazel:122:6: Error while validating output TreeArtifact File:[[<execution_root>]bazel-out/k8-fastbuild/bin]external/cyclonedds/cyclonedds/include : Failed to resolve relative path dds/dds.h inside TreeArtifact /home/user/.cache/bazel/_bazel_user/97780932f72da4bf457551d43f4a7dc9/execroot/com_github_mvukov_rules_ros2/bazel-out/k8-fastbuild/bin/external/cyclonedds/cyclonedds/include. The associated file is either missing or is an invalid symlink.

Target @@cyclonedds//:cyclonedds failed to build

I am at version 0.10.1 of this repo, as indicated here.

I'm open to suggestions.

I tried: bazel clean --expunge, didn't help.
