-# CMAKE_PARSE_ARGUMENTS(<prefix> <options> <one_value_keywords> <multi_value_keywords> args...)
-#
-# CMAKE_PARSE_ARGUMENTS() is intended to be used in macros or functions for
-# parsing the arguments given to that macro or function.
-# It processes the arguments and defines a set of variables which hold the
-# values of the respective options.
-#
-# The <options> argument contains all options for the respective macro,
-# i.e. keywords which can be used when calling the macro without any value
-# following, like e.g. the OPTIONAL keyword of the install() command.
-#
-# The <one_value_keywords> argument contains all keywords for this macro
-# which are followed by one value, like e.g. DESTINATION keyword of the
-# install() command.
-#
-# The <multi_value_keywords> argument contains all keywords for this macro
-# which can be followed by more than one value, like e.g. the TARGETS or
-# FILES keywords of the install() command.
-#
-# When done, CMAKE_PARSE_ARGUMENTS() will have defined for each of the
-# keywords listed in <options>, <one_value_keywords> and
-# <multi_value_keywords> a variable composed of the given <prefix>
-# followed by "_" and the name of the respective keyword.
-# These variables will then hold the respective value from the argument list.
-# For the <options> keywords this will be TRUE or FALSE.
-#
-# All remaining arguments are collected in a variable
-# <prefix>_UNPARSED_ARGUMENTS, this can be checked afterwards to see whether
-# your macro was called with unrecognized parameters.
-#
-# As an example here a my_install() macro, which takes similar arguments as the
-# real install() command:
-#
-# function(MY_INSTALL)
-# set(options OPTIONAL FAST)
-# set(oneValueArgs DESTINATION RENAME)
-# set(multiValueArgs TARGETS CONFIGURATIONS)
-# cmake_parse_arguments(MY_INSTALL "${options}" "${oneValueArgs}" "${multiValueArgs}" ${ARGN} )
-# ...
-#
-# Assume my_install() has been called like this:
-# my_install(TARGETS foo bar DESTINATION bin OPTIONAL blub)
-#
-# After the cmake_parse_arguments() call the macro will have set the following
-# variables:
-# MY_INSTALL_OPTIONAL = TRUE
-# MY_INSTALL_FAST = FALSE (this option was not used when calling my_install()
-# MY_INSTALL_DESTINATION = "bin"
-# MY_INSTALL_RENAME = "" (was not used)
-# MY_INSTALL_TARGETS = "foo;bar"
-# MY_INSTALL_CONFIGURATIONS = "" (was not used)
-# MY_INSTALL_UNPARSED_ARGUMENTS = "blub" (no value expected after "OPTIONAL"
-#
-# You can the continue and process these variables.
-#
-# Keywords terminate lists of values, e.g. if directly after a one_value_keyword
-# another recognized keyword follows, this is interpreted as the beginning of
-# the new option.
-# E.g. my_install(TARGETS foo DESTINATION OPTIONAL) would result in
-# MY_INSTALL_DESTINATION set to "OPTIONAL", but MY_INSTALL_DESTINATION would
-# be empty and MY_INSTALL_OPTIONAL would be set to TRUE therefor.
