+# 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.
