Subject: [PATCH] chore: make --shared-[...]-path work on Windows (#41)

The `-L<path>` syntax isn't recognized by link.exe, and gyp doesn't
translate it properly. Without this, link.exe generates the following
warning and fails to link:

```
LINK : warning LNK4044: unrecognized option '/LC:/Users/nornagon/...'; ignored
```
