Software Life cycle

Foundation Phase

1. Planning

Building Phase

5. Implementation (tools) 2. Gathering requirements 6. Testing (tools) 3. Analysis 4. Design/Architecture 7. Deployment (tools) 8. Maintenance

What is cmake ?

 Family of tool set  Open Source build system  Building tool – cmake  Testing tool – ctest (Automating)  Packaging tool – cpack

What cmake is not?

 Not a compiler  Not an editor  Not a scripting language  Not a compressing tool like Tar or zip  Not a package management system like rpm or deb  Not a test automation system  But it is a tool which interact with all of the above

cmake as a building tool

 Generates makefiles and workspaces to be used by compiler environment  Same version of CmakeLists.txt can work across different platforms  Easy to use  Can inspect the system which it is running on and make its intelligent decisions

cmake some syntax

 cmake_minimum_required ( VERSION 2.x )  project ( project_name )  include_directories( list of directories ) this is just like – I option in make  link_directories ( list of directories ) this is just like – L option in make  add_executable ( name of binary - target )  add_library ( name of library – target )

cmake other nice things

 target_link_libraries (list of libraries)  Define project_major_version (xxx)  Define project_minor_version (xxx)  Code generation support  Exectuting custom commands  Optional settings  Platform based settings (Windows, Linux, mac)

cmake commands

 cmake –options -to –specify  Cmake can be run in any place  Generates makefiles and cache files which remembers a lot of details  Make (targets - install, package, test)

Packaging - cpack

 can be used with cmake  can be used without cmake  can be used to package binary package  can be used to package source pacakge  can generate rpm, deb, stgz packages for linux  can generate windows installers  can generate mac os packages

cpack command usage

 To build package  Make package  Cpack –G RPM  Cpack –G DEB  Cpack –G TGZ;STGZ  Cpack –G NSIS (null soft installer for windows)  Cpack –G zip (f0r windows)  Some other options –C for configuration file –D define

cpack configuration

 Set package description  Set package version  Set package generator  Set OS specifics  Set install directives  Set output directives

cpack - example

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")

ctest

 ENABLE_TESTING()  ADD_TEST()  Do_test()

Some of the Projects with Cmake

 KDE  MySql  Compiz – opengl compositing window manager  Vispack – C++ library for processing images and surfaces  BIAS – Basic Image AlgorithmS –in C++  GoLib – general C++ library  XDMG – eXtensible Data Model and Format

Support Request

 I am developing a perl utility to convert a make system to cmake system  Need Support  People who can use it in their environments  People who can extend the utility  People who can do code reviews and help better it
