# 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. |

# ----------------------------- |

|
# |
||||
|
# |
||||
|
# |
||||
|
# 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}]") |
