FindBISONΒΆ
Find bison executable and provide a macro to generate custom build rules.
The module defines the following variables:
BISON_EXECUTABLE- path to the
bisonprogram 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 macro:
BISON_TARGET(<Name> <YaccInput> <CodeOutput>
[COMPILE_FLAGS <flags>]
[DEFINES_FILE <file>]
[VERBOSE [<file>]]
[REPORT_FILE <file>]
)
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.
The options are:
COMPILE_FLAGS <flags>- Specify flags to be added to the
bisoncommand line. DEFINES_FILE <file>- Specify a non-default header
<file>to be generated bybison. VERBOSE [<file>]- Tell
bisonto write a report file of the grammar and parser. If<file>is given, it specifies path the report file is copied to.[<file>]is left for backward compatibility of this module. UseVERBOSE REPORT_FILE <file>. REPORT_FILE <file>- Specify a non-default report
<file>, if generated.
The macro defines the following variables:
BISON_<Name>_DEFINEDTrueis the macro ran successfullyBISON_<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- All files generated by bison including the source, the header and the report
BISON_<Name>_COMPILE_FLAGS- Options used in the
bisoncommand line
Example usage:
find_package(BISON)
BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp
DEFINES_FILE ${CMAKE_CURRENT_BINARY_DIR}/parser.h)
add_executable(Foo main.cpp ${BISON_MyParser_OUTPUTS})
