| ''CPack'' is a software packaging tool distributed with [http://www.cmake.org
| | This page has moved [https://gitlab.kitware.com/cmake/community/wikis/doc/cpack/Packaging-With-CPack here]. |
| CMake]. 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:
| |
| | |
| <pre><nowiki>INCLUDE(Cpack)</nowiki></pre>
| |
| | |
| 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: | |
| | |
| <pre><nowiki>Run CPack packaging tool...

| CPack: Create package using STGZ
| |
| CPack: Install projects

| |
| | |
| 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:
| |
| | |
| <pre><nowiki>
| |
| 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_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")

| =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:
| |
| | |
| <pre><nowiki>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")</nowiki></pre>
| |
| | |
| 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 ...

| =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
| |
| complex project into a simple installer.
