-# 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>
-# [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.
-# Use the option CONFIG_MODE if your FindXXX.cmake module is a wrapper for
-# a find_package(... NO_MODULE) call, in this case all the information
-# provided by the config-mode of find_package() will be evaluated
-# automatically.
-# 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.
