# - Find Ragel executable and provides macros to generate custom build rules
|
||||
# The module defines the following variables:
|
||||
#
|
||||
# RAGEL_EXECUTABLE - path to the bison program
|
||||
# RAGEL_VERSION - version of bison
|
||||
# RAGEL_FOUND - true if the program was found
|
||||
#
|
||||
# If ragel is found, the module defines the macros:
|
||||
#
|
||||
# RAGEL_TARGET(<Name> <RagelInp> <CodeOutput>
|
||||
# [COMPILE_FLAGS <string>])
|
||||
#
|
||||
# which will create a custom rule to generate a state machine. <RagelInp> is
|
||||
# the path to a Ragel file. <CodeOutput> is the name of the source file
|
||||
# generated by ragel. If COMPILE_FLAGS option is specified, the next
|
||||
# parameter is added in the bison command line.
|
||||
#
|
||||
# The macro defines a set of variables:
|
||||
# RAGEL_${Name}_DEFINED - true is the macro ran successfully
|
||||
# RAGEL_${Name}_INPUT - The input source file, an alias for <RagelInp>
|
||||
# RAGEL_${Name}_OUTPUT_SOURCE - The source file generated by ragel
|
||||
# RAGEL_${Name}_OUTPUT_HEADER - The header file generated by ragel
|
||||
# RAGEL_${Name}_OUTPUTS - The sources files generated by ragel
|
||||
# RAGEL_${Name}_COMPILE_FLAGS - Options used in the ragel command line
|
||||
#
|
||||
# ====================================================================
|
||||
# Example:
|
||||
#
|
||||
# find_package(RAGEL) # or e.g.: find_package(RAGEL 6.6 REQUIRED)
|
||||
# RAGEL_TARGET(MyMachine machine.rl ${CMAKE_CURRENT_BINARY_DIR}/machine.cc)
|
||||
# add_executable(Foo main.cc ${RAGEL_MyMachine_OUTPUTS})
