CMake

Welcome to CMake, the cross-platform, open-source make system. CMake is used to control the software compilation process using simple platform and compiler independent configuration files. CMake generates native makefiles and workspaces that can be used in the compiler environment of your choice. CMake is quite sophisticated: it is possible to support complex environments requiring system configuration, pre-processor generation, code generation, and template instantiation.

You will find here not only documentation for CMake, but also for CPack and CTest.

Converters from other buildsystems to CMake

All converters listed here are not "complete", i.e. the generated CMake files are not 100% finished, in all cases some work is left for the developer.

automake/autotools/autoconf

• am2cmake (requires Ruby) Converts automake/autotools/libtool based projects to CMake, specialized in converting from KDE 3 to KDE 4, should also work for others. This one has been used for converting the KDE buildsystem to CMake.

• Alternative Automake2CMake (requires PHP) Converts KDevelop projects that use automake to CMake.

• Converting autoconf tests

qmake

• qmake converter (requires Ruby) Converts projects that use Qt's qmake.

Visual Studio

• vcproj2cmake.rb (requires Ruby) SourceForge project Creates and maintains CMakeLists.txt files by extracting info from Visual Studio project files. Elaborate script for development side-by-side the updated original static .vcproj files, supports script hooks and powerful definition mappings. Patches and new project members very welcome. Older script versions below:
  • Original vcproj2cmake.rb version (requires Ruby)
  • Slightly newer version here vcproj2cmake.rb, see:User_talk:Dweeves for details
• vcproj2cmake.ps1(PowerShell version) Creates CMakeLists.txt. it supports vcproj configuration and detect 'exclude from build' option
• folders4cmake (requires Java) Use Visual Studio project files to generate corresponding "source_group" information that you can use inside your own CMake scripts. Supports Visual Studio 9/10 project files (full round-trip possible).

Basic CMakeLists.txt from-scratch-generator

• gencmake (requires Ruby) Creates basic CMakeLists.txt files from looking at the existing files.
• CMakeListGenerator (Win32) Creates complete CMakeLists.txt files as described in the README using a combination of file and directory structure analysis. Supports resolving dependencies between multiple archives.
