[VERBOSE [<file>]] was my hope, but it's not easy. Since FindBISON now uses CMakeParseArguments, a keyword can't be used both as an option and as a one-value keyword. Possible solutions are: - Splitting [VERBOSE <file>] into [VERBOSE] (just `--verbose`) and [VERBOSE_FILE <file>] (`--verbose` and copy). It breaks the compatibility slightly, but I think this is an approvable break even without REPORT_FILE because there was no choice to get just default-named output file. In this case, "VERBOSE", "VERBOSE REPORT_FILE <file>" or "VERBOSE_FILE <file>" or any combinations can be used. - Let [VERBOSE <file>] and [REPORT_FILE <file>] independently exist. [VERBOSE <file>] means `--verbose` and copying to <file>, and [REPORT_FILE <file>] means `--report-file <file>` *and `--verbose`*. cf. In bison, `--report-file <file>` does not imply `--verbose`. - Extending CMakeParseArguments so a one-value keyword can be also used as options when it's passed both in <options> and <one_value_keywords>. Then combinations "VERBOSE", "VERBOSE <file>", "VERBOSE REPORT_FILE <file>", "VERBOSE <file> REPORT_FILE <file>" can be used. - Not using CMakeParseArguments. Sorry for making mistake. I was thinking wrong about how CMakeParseArguments works.
