#
# px4_parse_function_args
#
# This function simplifies usage of the cmake_parse_arguments module.
# It is intended to be called by other functions.
#
# Usage:
# px4_parse_function_args(
# NAME <name>
# [ OPTIONS <list> ]
# [ ONE_VALUE <list> ]
# [ MULTI_VALUE <list> ]
# REQUIRED <list>
# ARGN <ARGN>)
#
# Input:
# NAME : the name of the calling function
# OPTIONS : boolean flags
# ONE_VALUE : single value variables
# MULTI_VALUE : multi value variables
# REQUIRED : required arguments
# ARGN : the function input arguments, typically ${ARGN}
#
# Output:
# The function arguments corresponding to the following are set:
# ${OPTIONS}, ${ONE_VALUE}, ${MULTI_VALUE}
#
# Example:
# function test()
# px4_parse_function_args(
# NAME TEST
# ONE_VALUE NAME
# MULTI_VALUE LIST
# REQUIRED NAME LIST
# ARGN ${ARGN})
# message(STATUS "name: ${NAME}")
# message(STATUS "list: ${LIST}")
# endfunction()
#
# test(NAME "hello" LIST a b c)
#
# OUTPUT:
# name: hello
# list: a b c

#
# px4_join
#
# This function joins a list with a given separator. If list is not
# passed, or is sent "", this will return the empty string.
#
# Usage:
# px4_join(OUT ${OUT} [ LIST ${LIST} ] GLUE ${GLUE})
#
# Input:
# LIST : list to join
# GLUE : separator to use
#
# Output:
# OUT : joined list
#
# Example:
# px4_join(OUT test_join LIST a b c GLUE ";")
# test_join would then be:
# "a;b;c"

#
# px4_add_module
#
# This function builds a static library from a module description.
#
# Usage:
# px4_add_module(MODULE <string>
# [ MAIN <string> ]
# [ STACK <string> ] !!!!!DEPRECATED, USE STACK_MAIN INSTEAD!!!!!!!!!
# [ STACK_MAIN <string> ]
# [ STACK_MAX <string> ]
# [ COMPILE_FLAGS <list> ]
# [ INCLUDES <list> ]
# [ DEPENDS <string> ]
# [ EXTERNAL ]
# )
#
# Input:
# MODULE : unique name of module
# MAIN : entry point, if not given, assumed to be library
# STACK : deprecated use stack main instead
# STACK_MAIN : size of stack for main function
# STACK_MAX : maximum stack size of any frame
# COMPILE_FLAGS : compile flags
# LINK_FLAGS : link flags
# SRCS : source files
# INCLUDES : include directories
# DEPENDS : targets which this module depends on
# EXTERNAL : flag to indicate that this module is out-of-tree
# UNITY_BUILD : merge all source files and build this module as a single compilation unit
#
# Output:
# Static library with name matching MODULE.
#
# Example:
# px4_add_module(MODULE test
# SRCS
# file.cpp
# STACK_MAIN 1024
# DEPENDS
# git_nuttx
# )
