-# CMakeParseArguments
-# -------------------
-#
-#
-#
-# 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 then 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.

-# FindPackageHandleStandardArgs
-# -----------------------------
-#
-#
-#
-# FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> ...  )
-#
-# This function is intended to be used in FindXXX.cmake modules files.
-# It handles the REQUIRED, QUIET and version-related arguments to
-# find_package().  It also sets the <packagename>_FOUND variable.  The
-# package is considered found if all variables <var1>...  listed contain
-# valid results, e.g.  valid filepaths.
-#
-# There are two modes of this function.  The first argument in both
-# modes is the name of the Find-module where it is called (in original
-# casing).
-#
-# The first simple mode looks like this:
-#
-# ::
-#
-#     FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name>
-#       (DEFAULT_MSG|"Custom failure message") <var1>...<varN> )
-#
-# If the variables <var1> to <varN> are all valid, then
-# <UPPERCASED_NAME>_FOUND will be set to TRUE.  If DEFAULT_MSG is given
-# as second argument, then the function will generate itself useful
-# success and error messages.  You can also supply a custom error
-# message for the failure case.  This is not recommended.
-#
-# The second mode is more powerful and also supports version checking:
-#
-# ::
-#
-#     FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME
-#       [FOUND_VAR <resultVar>]
-#       [REQUIRED_VARS <var1>...<varN>]
-#       [VERSION_VAR   <versionvar>]
-#       [HANDLE_COMPONENTS]
-#       [CONFIG_MODE]
-#       [FAIL_MESSAGE "Custom failure message"] )
-#
-# In this mode, the name of the result-variable can be set either to
-# either <UPPERCASED_NAME>_FOUND or <OriginalCase_Name>_FOUND using the
-# FOUND_VAR option.  Other names for the result-variable are not
-# allowed.  So for a Find-module named FindFooBar.cmake, the two
-# possible names are FooBar_FOUND and FOOBAR_FOUND.  It is recommended
-# to use the original case version.  If the FOUND_VAR option is not
-# used, the default is <UPPERCASED_NAME>_FOUND.
-#
-# As in the simple mode, if <var1> through <varN> are all valid,
-# <packagename>_FOUND will be set to TRUE.  After REQUIRED_VARS the
-# variables which are required for this package are listed.  Following
-# VERSION_VAR the name of the variable can be specified which holds the
-# version of the package which has been found.  If this is done, this
-# version will be checked against the (potentially) specified required
-# version used in the find_package() call.  The EXACT keyword is also
-# handled.  The default messages include information about the required
-# version and the version which has been actually found, both if the
-# version is ok or not.  If the package supports components, use the
-# HANDLE_COMPONENTS option to enable handling them.  In this case,
-# find_package_handle_standard_args() will report which components have
-# been found and which are missing, and the <packagename>_FOUND variable
-# will be set to FALSE if any of the required components (i.e.  not the
-# ones listed after OPTIONAL_COMPONENTS) are missing.  Use the option
-# CONFIG_MODE if your FindXXX.cmake module is a wrapper for a
-# find_package(...  NO_MODULE) call.  In this case VERSION_VAR will be
-# set to <NAME>_VERSION and the macro will automatically check whether
-# the Config module was found.  Via FAIL_MESSAGE a custom failure
-# message can be specified, if this is not used, the default message
-# will be displayed.
-#
-# Example for mode 1:
-#
-# ::
-#
-#     find_package_handle_standard_args(LibXml2  DEFAULT_MSG
-#       LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR)
-#
-#
-#
-# LibXml2 is considered to be found, if both LIBXML2_LIBRARY and
-# LIBXML2_INCLUDE_DIR are valid.  Then also LIBXML2_FOUND is set to
-# TRUE.  If it is not found and REQUIRED was used, it fails with
-# FATAL_ERROR, independent whether QUIET was used or not.  If it is
-# found, success will be reported, including the content of <var1>.  On
-# repeated Cmake runs, the same message won't be printed again.
-#
-# Example for mode 2:
-#
-# ::
-#
-#     find_package_handle_standard_args(LibXslt
-#       FOUND_VAR LibXslt_FOUND
-#       REQUIRED_VARS LibXslt_LIBRARIES LibXslt_INCLUDE_DIRS
-#       VERSION_VAR LibXslt_VERSION_STRING)
-#
-# In this case, LibXslt is considered to be found if the variable(s)
-# listed after REQUIRED_VAR are all valid, i.e.  LibXslt_LIBRARIES and
-# LibXslt_INCLUDE_DIRS in this case.  The result will then be stored in
-# LibXslt_FOUND .  Also the version of LibXslt will be checked by using
-# the version contained in LibXslt_VERSION_STRING.  Since no
-# FAIL_MESSAGE is given, the default messages will be printed.
-#
-# Another example for mode 2:
-#
-# ::
-#
-#     find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4)
-#     find_package_handle_standard_args(Automoc4  CONFIG_MODE)
-#
-# In this case, FindAutmoc4.cmake wraps a call to find_package(Automoc4
-# NO_MODULE) and adds an additional search directory for automoc4.  Here
-# the result will be stored in AUTOMOC4_FOUND.  The following
-# FIND_PACKAGE_HANDLE_STANDARD_ARGS() call produces a proper
-# success/error message.
