Introduction
|
|
^^^^^^^^^^^^
|
|
|
|
This module is automatically included by :module:`CPack`.
|
|
|
|
Certain binary installers (especially the graphical installers) generated
|
|
by CPack allow users to select individual application *components* to install.
|
|
This module allows developers to configure the packaging of such components.
|
|
|
|
Contents is assigned to components by the ``COMPONENT``
|
|
argument of CMake's :command:`install` command. Components can be
|
|
annotated with user-friendly names and descriptions, inter-component
|
|
dependencies, etc., and grouped in various ways to customize the
|
|
resulting installer, using the commands described below.
|
|
|
|
To specify different groupings for different CPack generators use
|
|
a CPACK_PROJECT_CONFIG_FILE.
|
|
|
|
Variables
|
|
^^^^^^^^^
|
|
|
|
The following variables influence the component-specific packaging:
|
|
|
|
.. 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.
|
|
|
|
Instead of specifying all the desired components, it is possible to obtain a
|
|
list of all defined components and then remove the unwanted ones from the
|
|
list. The :command:`get_cmake_property` command can be used to obtain the
|
|
``COMPONENTS`` property, then the :command:`list(REMOVE_ITEM)` command can be
|
|
used to remove the unwanted ones. For example, to use all defined components
|
|
except ``foo`` and ``bar``::
|
|
|
|
get_cmake_property(CPACK_COMPONENTS_ALL COMPONENTS)
|
|
list(REMOVE_ITEM CPACK_COMPONENTS_ALL "foo" "bar")
|
|
|
|
.. 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.
|
|
|
|
.. variable:: CPACK_COMPONENTS_GROUPING
|
|
|
|
Specify how components are grouped for multi-package component-aware CPack
|
|
generators.
|
|
|
|
Some generators like RPM or ARCHIVE (TGZ, ZIP, ...) may generate
|
|
several packages files when there are components, depending
|
|
on the value of this variable:
|
|
|
|
* ONE_PER_GROUP (default): create one package per component group
|
|
* IGNORE : create one package per component (ignore the groups)
|
|
* ALL_COMPONENTS_IN_ONE : create a single package with all requested
|
|
components
|
|
|
|
.. variable:: CPACK_COMPONENT_<compName>_DISPLAY_NAME
|
|
|
|
The name to be displayed for a component.
|
|
|
|
.. variable:: CPACK_COMPONENT_<compName>_DESCRIPTION
|
|
|
|
The description of a component.
|
|
|
|
.. variable:: CPACK_COMPONENT_<compName>_GROUP
|
|
|
|
The group of a component.
|
|
|
|
.. variable:: CPACK_COMPONENT_<compName>_DEPENDS
|
|
|
|
The dependencies (list of components) on which this component depends.
|
|
|
|
.. variable:: CPACK_COMPONENT_<compName>_HIDDEN
|
|
|
|
True if this component is hidden from the user.
|
|
|
|
.. variable:: CPACK_COMPONENT_<compName>_REQUIRED
|
|
|
|
True if this component is required.
|
|
|
|
.. variable:: CPACK_COMPONENT_<compName>_DISABLED
|
|
|
|
True if this component is not selected to be installed by default.

Add component
|
|
"""""""""""""
|
|
|
|
.. command:: cpack_add_component
|
|
|
|
Describe an installation component.

|
|
|
|
``compname`` is the name of an installation component, as defined by the
|
|
``COMPONENT`` argument of one or more CMake :command:`install` commands.
|
|
With the ``cpack_add_component`` command one can set a name, a description,
|
|
and other attributes of an installation component.
|
|
One can also assign a component to a component group.
|
|
|
|
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.
|
|
|
|
PLIST gives a filename that is passed to pkgbuild with the
|
|
``--component-plist`` argument when using the productbuild generator.
|
|
|
|
Add component group
|
|
"""""""""""""""""""
|
|
|
|
.. command:: cpack_add_component_group
|
|
|
|
Describes a group of related CPack installation components.
|
|
|
|
::
|
|
|
|
cpack_add_component_group(groupname
|
|
[DISPLAY_NAME name]

|
|
|
|
|
|
|
|
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.
|
|
|
|
Add installation type
|
|
"""""""""""""""""""""
|
|
|
|
.. command:: 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.
|
|
|
|
Configure downloads
|
|
"""""""""""""""""""
|
|
|
|
.. command:: 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 macOS, installers that download components on-the-fly can only
|
|
be built and installed on system using macOS 10.5 or later.
|
|
|
|
The site argument is a URL where the archives for downloadable
|
|
components will reside, e.g.,
|
|
https://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.
