There were a few places that options only took place *after* determining a build system, even though we have multiple that impact the search (eg. `defaultBuildSystem` and `searchPaths`). Additionally track project root and configuration paths separately, so that when searching for implicit workspaces we can make sure to skip creating duplicates.
