-# 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
-#
-# 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 ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp)
-# add_executable(Foo main.cpp ${BISON_MyParser_OUTPUTS})
