# - Find bison executable and provides macros to generate custom build rules
|
||||
# The module defined the following variables:
|
||||
# BISON_EXECUTABLE - path to the bison program
|
||||
# BISON_VERSION - version of bison
|
||||
# BISON_FOUND - true if the program was found
|
||||
# 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
|
||||
#
|
||||
# Example:
|
||||
# FIND_PACKAGE(BISON)
|
||||
# BISON_TARGET(MyParser parser.y ${PROJECT_BINARY_DIR}/parser.cpp)
|
||||
# ADD_EXECUTABLE(Foo main.cpp ${BISON_MyParser_OUTPUTS})

# - Find flex executable and provides a macro to generate custom build rules
|
||||
# The module defines the following variables:
|
||||
# FLEX_FOUND - true is flex executable is found
|
||||
# FLEX_VERSION - the version of flex
|
||||
# If flex is found on the system, the module provides the macro:
|
||||
# FLEX_TARGET(Name FlexInput FlexOutput [COMPILE_FLAGS <string>])
|
||||
# which creates a custom command to generate the <FlexOutput> file from
|
||||
# the <FlexInput> file. If COMPILE_FLAGS option is specified, the next
|
||||
# parameter is added to the flex command line. Name is an alias used to
|
||||
# get details of this custom command. Indeed the macro defines the
|
||||
# following variables:
|
||||
# FLEX_${Name}_DEFINED - true is the macro ran successfully
|
||||
# FLEX_${Name}_OUTPUTS - the source file generated by the custom rule, an
|
||||
# alias for FlexOutput
|
||||
# FLEX_${Name}_INPUT - the flex source file, an alias for ${FlexInput}
|
||||
#
|
||||
# Flex scanners oftenly use tokens defined by Bison: the code generated
|
||||
# by Flex depends of the header generated by Bison. This module also
|
||||
# defines a macro:
|
||||
# ADD_FLEX_BISON_DEPENDENCY(FlexTarget BisonTarget)
|
||||
# which adds the required dependency between a scanner and a parser
|
||||
# where <FlexTarget> and <BisonTarget> are the first parameters of
|
||||
# respectively FLEX_TARGET and BISON_TARGET macros.
|
||||
#
|
||||
# Example:
|
||||
# FIND_PACKAGE(BISON)
|
||||
# FIND_PACKAGE(FLEX)
|
||||
# BISON_TARGET(MyParser parser.y ${PROJECT_BINARY_DIR}/parser.cpp
|
||||
# FLEX_TARGET(MyScanner lexer.l ${PROJECT_BINARY_DIR}/lexer.cpp)
|
||||
# ADD_FLEX_BISON_DEPENDENCY(MyScanner MyParser)
