This could be fixed by moving the copy logic to a second COMMAND
argument to the add_custom_command for the actual bison invocation.

I think that can be added as a separate REPORT_FILE option that is
considered separately from the VERBOSE option and uses --report-file.
It could be an error if the discovered bison tool does not support
the option.
