I don't have any experience with external projects so I can't help you
there, but two suggestsions/ideas:

1. Why do you need to nest one project inside the other? I think you
will have less trouble if you treat each one as its own independent
project.

2. Use add_subdirectory() instead of add_external_project() to hook
these two projects together.
