> We typically discourage usage of the id properties (the only use-case are Probes for the lack of other syntax) since Qbs is more «context» dependent and we provide some «magic» variables such as «product», «importingProduct» and so on.
> 
> You can use id prop if it works for you (but note that for e.g. Depends items id is not the id of the Depends item itself, but and alias for the imported module).
> 
> There are some other ways do do this. First, you can introduce an intermediate property to resolve the conflict:
> 
> MyProject {
>   installDir: "myfolder"
>   property string _temp: installDir
> 
>   MyProject {
>       installDir: _temp + "/mysubfolder"
>   }
> }
> 
> You can also try using «parent» variable but that’s not documented either and I’m not sure it’s OK to use it.
