Well, maybe there are better ways to do it, but we have a number of 
restrictions.

Ok, so you mean copying the entire framework to a staging directory, something 
like a "test-tree". Then we add test resources and run the test suite there. 
Sounds reasonable, I will investigate.
Certainly we had to consider ordering issues too, because all external headers 
and libraries must be copied in first, before copying to the test-tree.

Good point. Ideally we'd just copy them in again before running the test suite. 
Unlike I expected, this doesn't work at the moment. Maybe I should get this 
done first:

  $ cmake -GNinja ...
  $ ninja check-lldb
  $ ninja install
  $ ninja check-lldb

Which other test suite invocation(s) should I verify?
