Using https://github.com/arnetheduck/nora-poc/tree/1c5779ccb329a912b4e8f86d0cda0056488419aa as example and running nimble develop --withDependencies -l followed by nimble setup results in a paths file that failed to develop 2 deps:

...
--path:"/nora/nimbledeps/pkgs2/nim-2.2.6-b3179cffd77e51d16ea343b5493d895e8bc8c085"
--path:"/nora/nimbledeps/pkgs2/seaqt-0.6.4.0-ccfc438e327af82ba1d2146e1d24f033f7191bb6"
...

Both of these should be in vendor - seaqt is special in that it's using a branch:

requires   "https://github.com/seaqt/nim-seaqt.git#qt-6.4"
