Build binary and source package installers.
The CPack module generates binary and source installers in a variety of formats using the cpack program. Inclusion of the CPack module adds two new build targets, package
and package_source
, which build the binary and source installers respectively. The generated binary installers contain everything installed via CMake’s install()
command (and the deprecated install_files()
, install_programs()
and install_targets()
commands).
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. See CPackComponent
module for further details.
The CPACK_GENERATOR
variable has different meanings in different contexts. In a CMakeLists.txt
file, CPACK_GENERATOR
is a list of generators: and when cpack
is run with no other arguments, it will iterate over that list and produce one package for each generator. In a CPACK_PROJECT_CONFIG_FILE
, CPACK_GENERATOR
is a string naming a single generator. If you need per-cpack-generator logic to control other cpack settings, then you need a CPACK_PROJECT_CONFIG_FILE
.
The CMake source tree itself contains a CPACK_PROJECT_CONFIG_FILE
. See the top level file CMakeCPackOptions.cmake.in
for an example.
If set, the CPACK_PROJECT_CONFIG_FILE
is included automatically on a per-generator basis. It only need contain overrides.
Here’s how it works:
cpack
runsCPackConfig.cmake
-G
command line option, or if no such option was specified, over the list of generators given by the CPACK_GENERATOR
variable set in the CPackConfig.cmake
input file.CPACK_GENERATOR
to the one currently being iteratedCPACK_PROJECT_CONFIG_FILE
This is the key: For each generator listed in CPACK_GENERATOR
in CPackConfig.cmake
, cpack will reset CPACK_GENERATOR
internally to the one currently being used and then include the CPACK_PROJECT_CONFIG_FILE
.
Before including this CPack module in your CMakeLists.txt
file, there are a variety of variables that can be set to customize the resulting installers. The most commonly-used variables are:
CPACK_PACKAGE_NAME
The name of the package (or application). If not specified, it defaults to the project name.
CPACK_PACKAGE_VENDOR
The name of the package vendor. (e.g., “Kitware”). The default is “Humanity”.
CPACK_PACKAGE_DIRECTORY
The directory in which CPack is doing its packaging. If it is not set then this will default (internally) to the build dir. This variable may be defined in a CPack config file or from the cpack
command line option -B
. If set, the command line option overrides the value found in the config file.
CPACK_PACKAGE_VERSION_MAJOR
Package major version. This variable will always be set, but its default value depends on whether or not version details were given to the project()
command in the top level CMakeLists.txt file. If version details were given, the default value will be CMAKE_PROJECT_VERSION_MAJOR
. If no version details were given, a default version of 0.1.1 will be assumed, leading to CPACK_PACKAGE_VERSION_MAJOR
having a default value of 0.
CPACK_PACKAGE_VERSION_MINOR
Package minor version. The default value is determined based on whether or not version details were given to the project()
command in the top level CMakeLists.txt file. If version details were given, the default value will be CMAKE_PROJECT_VERSION_MINOR
, but if no minor version component was specified then CPACK_PACKAGE_VERSION_MINOR
will be left unset. If no project version was given at all, a default version of 0.1.1 will be assumed, leading to CPACK_PACKAGE_VERSION_MINOR
having a default value of 1.
CPACK_PACKAGE_VERSION_PATCH
Package patch version. The default value is determined based on whether or not version details were given to the project()
command in the top level CMakeLists.txt file. If version details were given, the default value will be CMAKE_PROJECT_VERSION_PATCH
, but if no patch version component was specified then CPACK_PACKAGE_VERSION_PATCH
will be left unset. If no project version was given at all, a default version of 0.1.1 will be assumed, leading to CPACK_PACKAGE_VERSION_PATCH
having a default value of 1.
CPACK_PACKAGE_DESCRIPTION
A description of the project, used in places such as the introduction screen of CPack-generated Windows installers. If not set, the value of this variable is populated from the file named by CPACK_PACKAGE_DESCRIPTION_FILE
.
CPACK_PACKAGE_DESCRIPTION_FILE
A text file used to describe the project when CPACK_PACKAGE_DESCRIPTION
is not explicitly set. The default value for CPACK_PACKAGE_DESCRIPTION_FILE
points to a built-in template file Templates/CPack.GenericDescription.txt
.
CPACK_PACKAGE_DESCRIPTION_SUMMARY
Short description of the project (only a few words). If the CMAKE_PROJECT_DESCRIPTION
variable is set, it is used as the default value, otherwise the default will be a string generated by CMake based on CMAKE_PROJECT_NAME
.
CPACK_PACKAGE_HOMEPAGE_URL
Project homepage URL. The default value is taken from the CMAKE_PROJECT_HOMEPAGE_URL
variable, which is set by the top level project()
command, or else the default will be empty if no URL was provided to project()
.
CPACK_PACKAGE_FILE_NAME
The name of the package file to generate, not including the extension. For example, cmake-2.6.1-Linux-i686
. The default value is:
${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}-${CPACK_SYSTEM_NAME}
CPACK_PACKAGE_INSTALL_DIRECTORY
Installation directory on the target system. This may be used by some CPack generators like NSIS to create an installation directory e.g., “CMake 2.5” below the installation prefix. All installed elements will be put inside this directory.
CPACK_PACKAGE_ICON
A branding image that will be displayed inside the installer (used by GUI installers).
CPACK_PACKAGE_CHECKSUM
An algorithm that will be used to generate an additional file with the checksum of the package. The output file name will be:
${CPACK_PACKAGE_FILE_NAME}.${CPACK_PACKAGE_CHECKSUM}
Supported algorithms are those listed by the string(<HASH>) command.
CPACK_PROJECT_CONFIG_FILE
CPack-time project CPack configuration file. This file is included at cpack time, once per generator after CPack has set CPACK_GENERATOR
to the actual generator being used. It allows per-generator setting of CPACK_*
variables at cpack time.
CPACK_RESOURCE_FILE_LICENSE
License to be embedded in the installer. It will typically be displayed to the user by the produced installer (often with an explicit “Accept” button, for graphical installers) prior to installation. This license file is NOT added to the installed files but is used by some CPack generators like NSIS. If you want to install a license file (may be the same as this one) along with your project, you must add an appropriate CMake install()
command in your CMakeLists.txt
.
CPACK_RESOURCE_FILE_README
ReadMe file to be embedded in the installer. It typically describes in some detail the purpose of the project during the installation. Not all CPack generators use this file.
CPACK_RESOURCE_FILE_WELCOME
Welcome file to be embedded in the installer. It welcomes users to this installer. Typically used in the graphical installers on Windows and Mac OS X.
CPACK_MONOLITHIC_INSTALL
Disables the component-based installation mechanism. When set, the component specification is ignored and all installed items are put in a single “MONOLITHIC” package. Some CPack generators do monolithic packaging by default and may be asked to do component packaging by setting CPACK_<GENNAME>_COMPONENT_INSTALL
to TRUE
.
CPACK_GENERATOR
List of CPack generators to use. If not specified, CPack will create a set of options following the naming pattern CPACK_BINARY_<GENNAME>
(e.g. CPACK_BINARY_NSIS
) allowing the user to enable/disable individual generators. If the -G
option is given on the cpack
command line, it will override this variable and any CPACK_BINARY_<GENNAME>
options.
CPACK_OUTPUT_CONFIG_FILE
The name of the CPack binary configuration file. This file is the CPack configuration generated by the CPack module for binary installers. Defaults to CPackConfig.cmake
.
CPACK_PACKAGE_EXECUTABLES
Lists each of the executables and associated text label to be used to create Start Menu shortcuts. For example, setting this to the list ccmake;CMake
will create a shortcut named “CMake” that will execute the installed executable ccmake
. Not all CPack generators use it (at least NSIS, WIX and OSXX11 do).
CPACK_STRIP_FILES
List of files to be stripped. Starting with CMake 2.6.0, CPACK_STRIP_FILES
will be a boolean variable which enables stripping of all files (a list of files evaluates to TRUE
in CMake, so this change is compatible).
CPACK_VERBATIM_VARIABLES
If set to TRUE
, values of variables prefixed with CPACK_
will be escaped before being written to the configuration files, so that the cpack program receives them exactly as they were specified. If not, characters like quotes and backslashes can cause parsing errors or alter the value received by the cpack program. Defaults to FALSE
for backwards compatibility.
The following CPack variables are specific to source packages, and will not affect binary packages:
CPACK_SOURCE_PACKAGE_FILE_NAME
The name of the source package. For example cmake-2.6.1
.
CPACK_SOURCE_STRIP_FILES
List of files in the source tree that will be stripped. Starting with CMake 2.6.0, CPACK_SOURCE_STRIP_FILES
will be a boolean variable which enables stripping of all files (a list of files evaluates to TRUE
in CMake, so this change is compatible).
CPACK_SOURCE_GENERATOR
List of generators used for the source packages. As with CPACK_GENERATOR
, if this is not specified then CPack will create a set of options (e.g. CPACK_SOURCE_ZIP
) allowing users to select which packages will be generated.
CPACK_SOURCE_OUTPUT_CONFIG_FILE
The name of the CPack source configuration file. This file is the CPack configuration generated by the CPack module for source installers. Defaults to CPackSourceConfig.cmake
.
CPACK_SOURCE_IGNORE_FILES
Pattern of files in the source tree that won’t be packaged when building a source package. This is a list of regular expression patterns (that must be properly escaped), e.g., /CVS/;/\\.svn/;\\.swp$;\\.#;/#;.*~;cscope.*
The following variables are for advanced uses of CPack:
CPACK_CMAKE_GENERATOR
What CMake generator should be used if the project is a CMake project. Defaults to the value of CMAKE_GENERATOR
. Few users will want to change this setting.
CPACK_INSTALL_CMAKE_PROJECTS
List of four values that specify what project to install. The four values are: Build directory, Project Name, Project Component, Directory. If omitted, CPack will build an installer that installs everything.
CPACK_SYSTEM_NAME
System name, defaults to the value of CMAKE_SYSTEM_NAME
, except on Windows where it will be win32
or win64
.
CPACK_PACKAGE_VERSION
Package full version, used internally. By default, this is built from CPACK_PACKAGE_VERSION_MAJOR
, CPACK_PACKAGE_VERSION_MINOR
, and CPACK_PACKAGE_VERSION_PATCH
.
CPACK_TOPLEVEL_TAG
Directory for the installed files.
CPACK_INSTALL_COMMANDS
Extra commands to install components.
CPACK_INSTALLED_DIRECTORIES
Extra directories to install.
CPACK_PACKAGE_INSTALL_REGISTRY_KEY
Registry key used when installing this project. This is only used by installers for Windows. The default value is based on the installation directory.
CPACK_CREATE_DESKTOP_LINKS
List of desktop links to create. Each desktop link requires a corresponding start menu shortcut as created by CPACK_PACKAGE_EXECUTABLES
.
CPACK_BINARY_<GENNAME>
CPack generated options for binary generators. The CPack.cmake
module generates (when CPACK_GENERATOR
is not set) a set of CMake options (see CMake option()
command) which may then be used to select the CPack generator(s) to be used when building the package
target or when running cpack
without the -G
option.
