`compiler` dependency does not give access to compiler
.nimble:
```nim
requires "nim >= 1.6.16",
         "compiler"
```

```sh
nimble setup -l
   Warning: Using project local deps mode

nimble.paths:
```
arnetheduck@praeceps:~/src/nimph$ cat nimble.paths
--noNimblePath
```

notably, compiler path is missing (`compiler/` is not part of `nim` standard paths)
