I am not sure why mock would be different, but that file should be a
symlink, it is created during the initial run of cmake.

It was added in this patch:

commit 07764bc805ba8f50539a7b1e2655e86acbdb87ed

    mlx5: Export mlx5 direct verbs interface
    
    Install direct verbs header file into /usr/include/infiniband/
    folder and allow for possible users to explicitly include it
    into their applications.

And it is created by this call here:

+  rdma_install_symlink("${DEST_LINK_PATH}" "${VERBS_PROVIDER_DIR}/lib${DEST}-rdmav2.so")

Make sure there are no errors from the cmake step??
