* No OBJECT library targets - compilation with unit tests will take a lot more time. * No HANDLE_COMPONENTS in FindPackageHandleStandardArgs - added copy of the file (and its dependencies) from CMake 2.8.8.

# 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. |
