| # - Look for GNU Bison, the parser generator
| | This page has moved [https://gitlab.kitware.com/cmake/community/wikis/contrib/modules/UseBison here]. |
| # Based off a news post from Andy Cedilnik at Kitware
| |
| # Defines the following:
| |
| # BISON_EXECUTABLE - path to the bison executable
| |
| # BISON_FILE - parse a file with bison
| |
| # BISON_PREFIX_OUTPUTS - Set to true to make BISON_FILE produce prefixed
| |
| # symbols in the generated output based on filename.
| |
| # So for ${filename}.y, you'll get ${filename}parse(), etc.
| |
| # instead of yyparse().
| |
| # BISON_GENERATE_DEFINES - Set to true to make BISON_FILE output the matching
| |
| # .h file for a .c file. You want this if you're using
| |
| # flex.
