| 0 | 1 # - Look for GNU Bison, the parser generator |
| 2 # Based off a news post from Andy Cedilnik at Kitware | |
| 3 # Defines the following: | |
| 4 # BISON_EXECUTABLE - path to the bison executable | |
| 5 # BISON_FILE - parse a file with bison | |
| 6 # BISON_PREFIX_OUTPUTS - Set to true to make BISON_FILE produce prefixed | |
| 7 # symbols in the generated output based on filename. | |
| 8 # So for ${filename}.y, you'll get ${filename}parse(), etc. | |
| 9 # instead of yyparse(). | |
| 10 # BISON_GENERATE_DEFINES - Set to true to make BISON_FILE output the matching | |
| 11 # .h file for a .c file. You want this if you're using | |
| 12 # flex. | |
