# ccmake(1)

## Synopsis

    ccmake [<options>] (<path-to-source> | <path-to-existing-build>)

## Description

The “ccmake” executable is the CMake curses interface. Project configuration settings may be specified interactively through this GUI. Brief instructions are provided at the bottom of the terminal when the program is running.

CMake is a cross-platform build system generator. Projects specify their build process with platform-independent CMake listfiles included in each directory of a source tree with the name CMakeLists.txt. Users build a project by using CMake to generate a build system for a native tool on their platform.

## Options

`-C <initial-cache>`

  Pre-load a script to populate the cache.

  When cmake is first run in an empty build tree, it creates a CMakeCache.txt file and populates it with customizable settings for the project. This option may be used to specify a file from which to load cache entries before the first pass through the project’s cmake listfiles. The loaded entries take priority over the project’s default values. The given file should be a CMake script containing SET commands that use the CACHE option, not a cache-format file.

`-D <var>:<type>=<value>`

  Create a cmake cache entry.

  When cmake is first run in an empty build tree, it creates a CMakeCache.txt file and populates it with customizable settings for the project. This option may be used to specify a setting that takes priority over the project’s default value. The option may be repeated for as many cache entries as desired.

`-U <globbing_expr>`

  Remove matching entries from CMake cache.

  This option may be used to remove one or more variables from the CMakeCache.txt file, globbing expressions using * and ? are supported. The option may be repeated for as many cache entries as desired.

  Use with care, you can make your CMakeCache.txt non-working.

`-G <generator-name>`

  Specify a build system generator.

  CMake may support multiple native build systems on certain platforms. A generator is responsible for generating a particular build system. Possible generator names are specified in the Generators section.

`-T <toolset-name>`

  Specify toolset name if supported by generator.

  Some CMake generators support a toolset name to be given to the native build system to choose a compiler. This is supported only on specific generators:

      Visual Studio >= 10
      Xcode >= 3.0

  See native build system documentation for allowed toolset names.

`-A <platform-name>`

  Specify platform name if supported by generator.

  Some CMake generators support a platform name to be given to the native build system to choose a compiler or SDK. This is supported only on specific generators:

      Visual Studio >= 8

  See native build system documentation for allowed platform names.
