installs from everything fail...

Half the bins, benchmarks, tests are all missing and the stringzilla dep is pointing at a parent dir?

Start by inspecting the repository's installation and build configuration, especially the StringZilla dependency declaration and the definitions for bins, benchmarks, and tests. Reproduce an install from a clean checkout and compare the expected targets and dependency path with what the build exposes; done means the listed components install and the dependency resolves without referencing a parent directory.
