##section Variables concerning CPack Components
##end
##module
# - Build binary and source package installers
#
# The CPackComponent module is the module which handles
# the component part of CPack. See CPack module for
# general information about CPack.
#
# For certain kinds of binary installers (including the graphical
# installers on Mac OS X and Windows), CPack generates installers that
# allow users to select individual application components to
# install. The contents of each of the components are identified by
# the COMPONENT argument of CMake's INSTALL command. These components
# can be annotated with user-friendly names and descriptions,
# inter-component dependencies, etc., and grouped in various ways to
# customize the resulting installer. See the cpack_add_* commands,
# described below, for more information about component-specific
# installations.
#
# Component-specific installation allows users to select specific sets
# of components to install during the install process. Installation
# components are identified by the COMPONENT argument of CMake's
# INSTALL commands, and should be further described by the following
# CPack commands:
##end
#
##variable
#  CPACK_COMPONENTS_ALL - The list of component to install.
#
#The default value of this variable is computed by CPack
#and contains all components defined by the project. The
#user may set it to only include the specified components.
##end
#
##variable
#  CPACK_<GENNAME>_COMPONENT_INSTALL - Enable/Disable component install for
#  CPack generator <GENNAME>.
#
#Each CPack Generator (RPM, DEB, ARCHIVE, NSIS, DMG, etc...) has a legacy
#default behavior. e.g. RPM builds monolithic whereas NSIS builds component.
#One can change the default behavior by setting this variable to 0/1 or OFF/ON.
##end
##variable
#  CPACK_COMPONENTS_GROUPING - Specify how components are grouped for multi-package
#  component-aware CPack generators.
#
#Some generators like RPM or ARCHIVE family (TGZ, ZIP, ...) generates several
#packages files when asked for component packaging. They group the component
#differently depending on the value of this variable:
#  - ONE_PER_GROUP (default): creates one package file per component group
#  - ALL_COMPONENTS_IN_ONE : creates a single package with all (requested) component
#  - IGNORE : creates one package per component, i.e. IGNORE component group
#One can specify different grouping for different CPack generator by using
#a CPACK_PROJECT_CONFIG_FILE.
##end
##variable
#  CPACK_COMPONENT_<compName>_DISPLAY_NAME - The name to be displayed for a component.
##end
##variable
#  CPACK_COMPONENT_<compName>_DESCRIPTION - The description of a component.
##end
##variable
#  CPACK_COMPONENT_<compName>_GROUP - The group of a component.
##end
##variable
#  CPACK_COMPONENT_<compName>_DEPENDS - The dependencies (list of components)
#  on which this component depends.
##end
##variable
#  CPACK_COMPONENT_<compName>_REQUIRED - True is this component is required.
##end
##macro
#cpack_add_component - Describes a CPack installation component
#named by the COMPONENT argument to a CMake INSTALL command.
#
#  cpack_add_component(compname
#                      [DISPLAY_NAME name]
#                      [DESCRIPTION description]
#                      [HIDDEN | REQUIRED | DISABLED ]
#                      [GROUP group]
#                      [DEPENDS comp1 comp2 ... ]
#                      [INSTALL_TYPES type1 type2 ... ]
#                      [DOWNLOADED]
#                      [ARCHIVE_FILE filename])
#
#The cmake_add_component command describes an installation
#component, which the user can opt to install or remove as part of
#the graphical installation process. compname is the name of the
#component, as provided to the COMPONENT argument of one or more
#CMake INSTALL commands.
#
#DISPLAY_NAME is the displayed name of the component, used in
#graphical installers to display the component name. This value can
#be any string.
#
#DESCRIPTION is an extended description of the component, used in
#graphical installers to give the user additional information about
#the component. Descriptions can span multiple lines using "\n" as
#the line separator. Typically, these descriptions should be no
#more than a few lines long.
#
#HIDDEN indicates that this component will be hidden in the
#graphical installer, so that the user cannot directly change
#whether it is installed or not.
#
#REQUIRED indicates that this component is required, and therefore
#will always be installed. It will be visible in the graphical
#installer, but it cannot be unselected. (Typically, required
#components are shown greyed out).
#
#DISABLED indicates that this component should be disabled
#(unselected) by default. The user is free to select this component
#for installation, unless it is also HIDDEN.
#
#DEPENDS lists the components on which this component depends. If
#this component is selected, then each of the components listed
#must also be selected. The dependency information is encoded
#within the installer itself, so that users cannot install
#inconsistent sets of components.
#
#GROUP names the component group of which this component is a
#part. If not provided, the component will be a standalone
#component, not part of any component group. Component groups are
#described with the cpack_add_component_group command, detailed
#below.
#
#INSTALL_TYPES lists the installation types of which this component
#is a part. When one of these installations types is selected, this
#component will automatically be selected. Installation types are
#described with the cpack_add_install_type command, detailed below.
#
#DOWNLOADED indicates that this component should be downloaded
#on-the-fly by the installer, rather than packaged in with the
#installer itself. For more information, see the cpack_configure_downloads
# command.
#
#ARCHIVE_FILE provides a name for the archive file created by CPack
#to be used for downloaded components. If not supplied, CPack will
#create a file with some name based on CPACK_PACKAGE_FILE_NAME and
#the name of the component. See cpack_configure_downloads for more
#information.
##end
#
##macro
#cpack_add_component_group - Describes a group of related CPack
#installation components.
#
#  cpack_add_component_group(groupname
#                           [DISPLAY_NAME name]
#                           [DESCRIPTION description]
#                           [PARENT_GROUP parent]
#                           [EXPANDED]
#                           [BOLD_TITLE])
#
#The cpack_add_component_group describes a group of installation
#components, which will be placed together within the listing of
#options. Typically, component groups allow the user to
#select/deselect all of the components within a single group via a
#single group-level option. Use component groups to reduce the
#complexity of installers with many options. groupname is an
#arbitrary name used to identify the group in the GROUP argument of
#the cpack_add_component command, which is used to place a
#component in a group. The name of the group must not conflict with
#the name of any component.
#
#DISPLAY_NAME is the displayed name of the component group, used in
#graphical installers to display the component group name. This
#value can be any string.
#
#DESCRIPTION is an extended description of the component group,
#used in graphical installers to give the user additional
#information about the components within that group. Descriptions
#can span multiple lines using "\n" as the line
#separator. Typically, these descriptions should be no more than a
#few lines long.
#
#PARENT_GROUP, if supplied, names the parent group of this group.
#Parent groups are used to establish a hierarchy of groups,
#providing an arbitrary hierarchy of groups.
#
#EXPANDED indicates that, by default, the group should show up as
#"expanded", so that the user immediately sees all of the
#components within the group. Otherwise, the group will initially
#show up as a single entry.
#
#BOLD_TITLE indicates that the group title should appear in bold,
#to call the user's attention to the group.
##end
#
##macro
#cpack_add_install_type - Add a new installation type containing a
#set of predefined component selections to the graphical installer.
#
#  cpack_add_install_type(typename
#                         [DISPLAY_NAME name])
#
#The cpack_add_install_type command identifies a set of preselected
#components that represents a common use case for an
#application. For example, a "Developer" install type might include
#an application along with its header and library files, while an
#"End user" install type might just include the application's
#executable. Each component identifies itself with one or more
#install types via the INSTALL_TYPES argument to
#cpack_add_component.
#
#DISPLAY_NAME is the displayed name of the install type, which will
#typically show up in a drop-down box within a graphical
#installer. This value can be any string.
##end
#
##macro
#cpack_configure_downloads - Configure CPack to download selected
#components on-the-fly as part of the installation process.
#
#  cpack_configure_downloads(site
#                            [UPLOAD_DIRECTORY dirname]
#                            [ALL]
#                            [ADD_REMOVE|NO_ADD_REMOVE])
#
#The cpack_configure_downloads command configures installation-time
#downloads of selected components. For each downloadable component,
#CPack will create an archive containing the contents of that
#component, which should be uploaded to the given site. When the
#user selects that component for installation, the installer will
#download and extract the component in place. This feature is
#useful for creating small installers that only download the
#requested components, saving bandwidth. Additionally, the
#installers are small enough that they will be installed as part of
#the normal installation process, and the "Change" button in
#Windows Add/Remove Programs control panel will allow one to add or
#remove parts of the application after the original
#installation. On Windows, the downloaded-components functionality
#requires the ZipDLL plug-in for NSIS, available at:
#
#  http://nsis.sourceforge.net/ZipDLL_plug-in
#
#On Mac OS X, installers that download components on-the-fly can
#only be built and installed on system using Mac OS X 10.5 or
#later.
#
#The site argument is a URL where the archives for downloadable
#components will reside, e.g., http://www.cmake.org/files/2.6.1/installer/
#All of the archives produced by CPack should be uploaded to that location.
#
#UPLOAD_DIRECTORY is the local directory where CPack will create the
#various archives for each of the components. The contents of this
#directory should be uploaded to a location accessible by the URL given
#in the site argument. If omitted, CPack will use the directory
#CPackUploads inside the CMake binary directory to store the generated
#archives.
#
#The ALL flag indicates that all components be downloaded. Otherwise, only
#those components explicitly marked as DOWNLOADED or that have a specified
#ARCHIVE_FILE will be downloaded. Additionally, the ALL option implies
#ADD_REMOVE (unless NO_ADD_REMOVE is specified).
#
#ADD_REMOVE indicates that CPack should install a copy of the installer
#that can be called from Windows' Add/Remove Programs dialog (via the
#"Modify" button) to change the set of installed components. NO_ADD_REMOVE
#turns off this behavior. This option is ignored on Mac OS X.
