CMake is an open-source cross-platform build system generator.


CMake is especially useful if an application depends on several other directories (e.g. libraries) in addition to code or if certain parts need to be compiled and linked in a specific order. The build process is controlled by CMakeLists.txt files which consist of commands and arguments and must be present in all directories, including subdirectories. It is possible to use both predefined and custom commands.

Interactive usage

In order to modify the settings for the build process in an interactive GUI, change to the "build" directory of your project and execute the following command:

ccmake .

This will give you an overview of all arguments for the build process in alphabetical order. You can edit an option by pressing [enter]. Afterwards, make sure to configure your settings by pressing [c] and then [g] to generate, so that your changes will go into effect during the next build process.
