# 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.

#.rst:
# 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 python libraries
# This module finds if Python is installed and determines where the
# include files and libraries are. It also determines what the name of
# the library is. This code sets the following variables:
#
# PYTHONLIBS_FOUND - have the Python libs been found
# PYTHON_LIBRARIES - path to the python library
# PYTHON_INCLUDE_PATH - path to where Python.h is found (deprecated)
# PYTHON_INCLUDE_DIRS - path to where Python.h is found
# PYTHON_DEBUG_LIBRARIES - path to the debug library (deprecated)
# PYTHONLIBS_VERSION_STRING - version of the Python libs found (since CMake 2.8.8)
#
# The Python_ADDITIONAL_VERSIONS variable can be used to specify a list of
# version numbers that should be taken into account when searching for Python.
# You need to set this variable before calling find_package(PythonLibs).
#
# You can point to a preferred python install to use by setting the following
# to the point at the root directory of the python install:
#
# PYTHON_ROOT_DIR - The root directory of the python install
#
# If you'd like to specify the installation of Python to use, you should modify
# the following cache variables:
# PYTHON_LIBRARY - path to the python library
# PYTHON_INCLUDE_DIR - path to where Python.h is found
