Introduction

CPack is a software packaging tool distributed with [http://www.cmake.org CMake] since version 2.4.2. It uses the generators concept from CMake, to abstract package generation on specific platforms. It can be used with or without CMake, but it may depend on some software being installed on the system. For example, on Mac OSX, it relies on Xcode to be installed and on Windows it requires NSIS.

Using CPack with CMake

CMake comes with CPack module, which will generate appropriate CPack input file. To use this module, some CMake variables need to be set. These variables will be copied to the CPack input file.

A simple CMake section to use CPack from CMake is this:

INCLUDE(CPack)

This will generate new target in Makefile (or Visual Studio, or Xcode) called "package". By running this target, CPack will be invoked, which will generate all the packages. Example output of the "package" target of Makefile is:

Run CPack packaging tool...
CPack: Create package using STGZ
CPack: Install projects
CPack: - Run preinstall target for: CMake
CPack: - Install project: CMake
CPack: - Strip files
CPack: Compress package
CPack: Finalize package
CPack: Package /home/andy/CMake-bin/cmake-2.5.0-Linux-i686.sh generated.
CPack: Create package using TGZ
CPack: Install projects
CPack: - Run preinstall target for: CMake
CPack: - Install project: CMake
CPack: - Strip files
CPack: Compress package
CPack: Finalize package
CPack: Package /home/andy/CMake-bin/cmake-2.5.0-Linux-i686.tar.gz generated.
CPack: Create package using TZ
CPack: Install projects
CPack: - Run preinstall target for: CMake
CPack: - Install project: CMake
CPack: - Strip files
CPack: Compress package
CPack: Finalize package
CPack: Package /home/andy/CMake-bin/cmake-2.5.0-Linux-i686.tar.Z generated.

When adding line:

INCLUDE(CPack)

CMake module CPack.cmake will generate CPack configuration file called CPackConfig.cmake.

A more typical CMake list section for CPack configuration would be:

INCLUDE(InstallRequiredSystemLibraries)

SET(CPACK_PACKAGE_DESCRIPTION_SUMMARY "My funky project")
SET(CPACK_PACKAGE_VENDOR "Me, myself, and I")
SET(CPACK_PACKAGE_DESCRIPTION_FILE "${CMAKE_CURRENT_SOURCE_DIR}/ReadMe.txt")
SET(CPACK_RESOURCE_FILE_LICENSE "${CMAKE_CURRENT_SOURCE_DIR}/Copyright.txt")
SET(CPACK_PACKAGE_VERSION_MAJOR "1")
SET(CPACK_PACKAGE_VERSION_MINOR "3")
SET(CPACK_PACKAGE_VERSION_PATCH "2")
SET(CPACK_PACKAGE_INSTALL_DIRECTORY "CMake ${CMake_VERSION_MAJOR}.${CMake_VERSION_MINOR}")
IF(WIN32 AND NOT UNIX)
  # There is a bug in NSI that does not handle full unix paths properly. Make
  # sure there is at least one set of four (4) backlasshes.
  SET(CPACK_PACKAGE_ICON "${CMake_SOURCE_DIR}/Utilities/Release\\\\InstallIcon.bmp")
  SET(CPACK_NSIS_INSTALLED_ICON_NAME "bin\\\\MyExecutable.exe")
  SET(CPACK_NSIS_DISPLAY_NAME "${CPACK_PACKAGE_INSTALL_DIRECTORY} My Famous Project")
  SET(CPACK_NSIS_HELP_LINK "http:\\\\\\\\www.my-project-home-page.org")
  SET(CPACK_NSIS_URL_INFO_ABOUT "http:\\\\\\\\www.my-personal-home-page.com")
  SET(CPACK_NSIS_CONTACT "me@my-personal-home-page.com")
  SET(CPACK_NSIS_MODIFY_PATH ON)
ELSE(WIN32 AND NOT UNIX)
  SET(CPACK_STRIP_FILES "bin/MyExecutable")
  SET(CPACK_SOURCE_STRIP_FILES "")
ENDIF(WIN32 AND NOT UNIX)
SET(CPACK_PACKAGE_EXECUTABLES "MyExecutable" "My Executable")
INCLUDE(CPack)

CPack and INSTALL commands

CPack will internally use CMake's install mechanism to populate the package. The Install Commands page describes how to use the CMake's INSTALL command.

Using CPack without CMake

CPack can be used directly by specifying CPackConfig.cmake file. This file uses CMake syntax and has to contain several variables. Here is example CPackConfig.cmake files from CMake build directory on Linux system:

SET(CPACK_CMAKE_GENERATOR "Unix Makefiles")
SET(CPACK_GENERATOR "STGZ;TGZ;TZ")
SET(CPACK_INSTALL_CMAKE_PROJECTS "/home/andy/vtk/CMake-bin;CMake;ALL;/")
SET(CPACK_NSIS_DISPLAY_NAME "CMake 2.5")
SET(CPACK_OUTPUT_CONFIG_FILE "/home/andy/vtk/CMake-bin/CPackConfig.cmake")
SET(CPACK_PACKAGE_DESCRIPTION_FILE "/home/andy/vtk/CMake/Copyright.txt")
SET(CPACK_PACKAGE_DESCRIPTION_SUMMARY "CMake is a build tool")
SET(CPACK_PACKAGE_EXECUTABLES "ccmake;CMake")
SET(CPACK_PACKAGE_FILE_NAME "cmake-2.5.0-Linux-i686")
SET(CPACK_PACKAGE_INSTALL_DIRECTORY "CMake 2.5")
SET(CPACK_PACKAGE_INSTALL_REGISTRY_KEY "CMake 2.5.0")
SET(CPACK_PACKAGE_NAME "CMake")
SET(CPACK_PACKAGE_VENDOR "Kitware")
SET(CPACK_PACKAGE_VERSION "2.5.0")
SET(CPACK_PACKAGE_VERSION_MAJOR "2")
SET(CPACK_PACKAGE_VERSION_MINOR "5")
SET(CPACK_PACKAGE_VERSION_PATCH "0")
SET(CPACK_RESOURCE_FILE_LICENSE "/home/andy/vtk/CMake/Copyright.txt")
SET(CPACK_RESOURCE_FILE_README "/home/andy/vtk/CMake/Templates/CPack.GenericDescription.txt")
SET(CPACK_RESOURCE_FILE_WELCOME "/home/andy/vtk/CMake/Templates/CPack.GenericWelcome.txt")
SET(CPACK_SOURCE_GENERATOR "TGZ;TZ")
SET(CPACK_SOURCE_OUTPUT_CONFIG_FILE "/home/andy/vtk/CMake-bin/CPackSourceConfig.cmake")
SET(CPACK_SOURCE_PACKAGE_FILE_NAME "cmake-2.5.0")
SET(CPACK_SOURCE_STRIP_FILES "")
SET(CPACK_STRIP_FILES "bin/ccmake;bin/cmake;bin/cpack;bin/ctest")
SET(CPACK_SYSTEM_NAME "Linux-i686")
SET(CPACK_TOPLEVEL_TAG "Linux-i686")

These variables can be overwritten on the command line using the option "-D":

cpack -D CPACK_PACKAGE_VENDOR=Me -D CPACK_SYSTEM_NAME=super-duper-linux ...

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_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). bin/ccmake;bin/cmake;bin/cpack;bin/ctest
CPACK_SYSTEM_NAME System name Linux-i686

CPack Package Generators

Currently CPack features the following package generators:

TGZ
Tar GZip compressed packages.
STGZ
Self extracting Tar GZip compressed packages (needs /bin/sh, tar and gunzip for extracting).
NSIS
Nullsoft Installer. Requires NSIS for creating the package.
ZIP
ZIP compressed packages. Requires zip, WinZip or 7Zip for creating the package.
TBZ2
Tar BZip2 compressed packages. Requires bzip2 for creating the package.
TZ
Tar UNIX compress compressed packages.
PackageMaker (OSX only)
Mac OSX Package Maker packages. Requires Package Maker for creating the package.
OSXX11 (OSX only)
Mac OSX X11 Bundle. Requires hdiutil for creating the package.
CygwinBinary (Cygwin only)
Tar Bzip2 compressed Cygwin package. Requires bzip2 for creating the package.
CygwinSource (Cygwin only)
Tar Bzip2 compressed Cygwin source package. Requires bzip2 for creating the package.

RPM and deb packages are currently not supported, but you should look at RPM and Deb modules.

Here's a link to a workaround how to create RPMs using CMake and CPack: http://public.kitware.com/pipermail/cmake/2007-April/013562.html .

Conclusion

CPack is a powerful, easy to use, cross-platform packaging tool. Using a simple configuration file or using a CMake module, the author of a project can package a complex project into a simple installer.
