CMake: Unify error reporting for builddirmanager's information retrieval

Use a dedicated errrorMessage out parameter for error reporting in
the builddirmanager methods related to information retrieval. Those are
called after the parsing has finished.

This frees the errrorOccured signal of the builddirmanager to be used only
when the parsing itself has failed.
