Implicit dependencies file linking does not work in Windows

When running Robespierre in Windows, clicking on standard output file link for implicit dependencies give the following error message when using VSCode :

`The path '\' does not exist on this computer`

Start by reproducing the implicit-dependency file link on Windows in VSCode and trace how the standard output path is generated. Done means clicking the link opens the referenced file instead of reporting that the path '\' does not exist.
