-# 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.

-# 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 <UPPERCASED_NAME>_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 [REQUIRED_VARS <var1>...<varN>]

-#                                           [VERSION_VAR   <versionvar>]

-#                                           [HANDLE_COMPONENTS]

-#                                           [CONFIG_MODE]

-#                                           [FAIL_MESSAGE "Custom failure message"] )

-#

-# As above, if <var1> through <varN> are all valid, <UPPERCASED_NAME>_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 <NAME>_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(BISON  REQUIRED_VARS BISON_EXECUTABLE

-#                                             VERSION_VAR BISON_VERSION)

-# In this case, BISON is considered to be found if the variable(s) listed

-# after REQUIRED_VAR are all valid, i.e. BISON_EXECUTABLE in this case.

-# Also the version of BISON will be checked by using the version contained

-# in BISON_VERSION.

-# 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.

-# The following FIND_PACKAGE_HANDLE_STANDARD_ARGS() call produces a proper

-# success/error message.

+# 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 [REQUIRED_VARS <var1>...<varN>]
+#                                           [VERSION_VAR   <versionvar>]
+#                                           [HANDLE_COMPONENTS]
+#                                           [CONFIG_MODE]
+#                                           [FAIL_MESSAGE "Custom failure message"] )
+#
+# As above, if <var1> through <varN> are all valid, <UPPERCASED_NAME>_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 <NAME>_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(BISON  REQUIRED_VARS BISON_EXECUTABLE
+#                                             VERSION_VAR BISON_VERSION)
+# In this case, BISON is considered to be found if the variable(s) listed
+# after REQUIRED_VAR are all valid, i.e. BISON_EXECUTABLE in this case.
+# Also the version of BISON will be checked by using the version contained
+# in BISON_VERSION.
+# 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.
+# The following FIND_PACKAGE_HANDLE_STANDARD_ARGS() call produces a proper
+# success/error message.
