Subject: [PATCH 2/4] Patch OpenSSL POD docs for perl-5.16+

Stricter validation in recent Perl versions means the install
stage fails without these applied.

Should be harmless for earlier versions of perl.

+# <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.

+# FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details")
+#
+# This macro is intended to be used in FindXXX.cmake modules files.  It
+# will print a message once for each unique find result.  This is useful
+# for telling the user where a package was found.  The first argument
+# specifies the name (XXX) of the package.  The second argument
+# specifies the message to display.  The third argument lists details
+# about the find result so that if they change the message will be
+# displayed again.  The macro also obeys the QUIET argument to the
+# find_package command.
+#
+# Example:
+#
+# ::
+#
+#   if(X11_FOUND)
+#     FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}"
+#       "[${X11_X11_LIB}][${X11_INCLUDE_DIR}]")
