Thanks for the followup. Can do. Let me see if I can minimize the reproducer/reduce the number of cmake flags needed for ease first since the two-stage build has dependencies on libxml2 and zlib.

While I'm doing that, if you already have a fix, what I can do is patch it locally and get back to you on if it also fixes the issues we see.
