-#                         [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
-#   inconsitent 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.
-#
-#   cpack_add_component_group - Describes a group of related CPack
-#   installation components.
-#
-#     cpack_add_component_group(groupname
-#                              [DISPLAY_NAME name]

-#                              [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.
-#
-#   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.
-#
-#   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.

+# - 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:
+#
+#   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 ... ]

+#                         [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
+#   inconsitent 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.
+#
+#   cpack_add_component_group - Describes a group of related CPack
+#   installation components.
+#
+#     cpack_add_component_group(groupname
+#                              [DISPLAY_NAME name]

+#                              [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.
+#
+#   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.
+#
+#   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.
