You can use `cd V:/src/anygui && nimble develop` (well, might have to change it to be DOS-compatible but hopefully you get the idea).
This will create a symlink inside Nimble for `anygui` and point it to `V:/src/anygui`. Then you can use `requires "anygui"` in your .nimble file. You will run into some other issues though, conflicting packages like this aren't well supported yet.
