# - Find bison++ executable and provides macros to generate custom build rules
|
||||
# The module defines the following variables:
|
||||
#
|
||||
# BISON_EXECUTABLE - path to the bison program
|
||||
# BISON_VERSION - version of bison
|
||||
# BISON_FOUND - true if the program was found
|
||||
#
|
||||
# The minimum required version of bison can be specified using the
|
||||
# standard CMake syntax, e.g. find_package(BISON 2.1.3)
|
||||
#
|
||||
# If bison is found, the module defines the macros:
|
||||
# BISON_TARGET(<Name> <YaccInput> <CodeOutput> [VERBOSE <file>]
|
||||
# [COMPILE_FLAGS <string>])
|
||||
# which will create a custom rule to generate a parser. <YaccInput> is
|
||||
# the path to a yacc file. <CodeOutput> is the name of the source file
|
||||
# generated by bison. A header file is also be generated, and contains
|
||||
# the token list. If COMPILE_FLAGS option is specified, the next
|
||||
# parameter is added in the bison command line. if VERBOSE option is
|
||||
# specified, <file> is created and contains verbose descriptions of the
|
||||
# grammar and parser. The macro defines a set of variables:
|
||||
# BISON_${Name}_DEFINED - true is the macro ran successfully
|
||||
# BISON_${Name}_INPUT - The input source file, an alias for <YaccInput>
|
||||
# BISON_${Name}_OUTPUT_SOURCE - The source file generated by bison
|
||||
# BISON_${Name}_OUTPUT_HEADER - The header file generated by bison
|
||||
# BISON_${Name}_OUTPUTS - The sources files generated by bison
|
||||
# BISON_${Name}_COMPILE_FLAGS - Options used in the bison command line
|
||||
