CLion 2024.1 Help

Load/reload CMake

Load CMake

  • When a CMakeLists.txt file is detected under the project root, CLion loads its automatically.

    To manually load a CMakeLists.txt file, right-click it in the project tree and select Load CMake Project from the context menu:

    Loading an existing CMakeLists.txt file

Reload CMake on changes in CMakeLists.txt

  • By default, when you make changes in the CMakeLists.txt file, CLion shows a floating notification indicating that the project needs to be reloaded:

    CMake reload floating notification

    Click it or press the shortcut to reload CMake.

  • You can disable the floating notification in Settings | Advanced Settings | CMake:

    Advanced settings CMake floating notification

    In this case, the notification will look as follows, suggesting two options for project reload:

    CMake reload option
    • Reload changes

      In this case, you reload the project once, and all the subsequent changes in CMakeLists.txt will also require reloading.

    • Enable Auto-reload

      This option lets CLion silently reload the project on every change in your CMakeLists.txt.

      This is similar to selecting the Reload CMake project on editing CMakeLists.txt or other CMake configuration files checkbox in Settings | Build, Execution, Deployment | CMake:

      Enabling auto-reload in CMake settings

      Note that your project is reloaded automatically when you reset the CMake cache.

Disable CMake auto-reload

  • To completely disable automatic reload including external changes, go to Settings | Advanced Settings and set the Do not trigger CMake reload automatically checkbox:

    Disabling CMake reload

Reload CMake manually

To reload a project manually when needed, use one of the following options:

  • Call Find Action (Ctrl+Shift+A) and start typing reload cmake. Select the Reload CMake Project action.

  • In the main menu, go to File | Reload CMake Project or Tools | CMake | Reload CMake Project.

  • In CMake tool window, click .

Stop project reload

To stop the process of reloading a project, use one of the following options:

  1. Call Find Action (Ctrl+Shift+A) and start typing stop cmake. Select the Stop CMake Project Reload action.

  2. In CMake tool window, click .

Manage run/debug configurations on project reload

When you add or delete targets and reload your project, CLion automatically creates or deletes the corresponding run/debug configurations.

You can control this behavior in Settings | Advanced Settings:

create or delete configurations for targets automatically

    Unload CMake

    Use the Unload CMake Project action when you need to unlink your project off the CMake build system completely or when CLion loads a CMakeLists.txt script, but you want to use another one for your project.

    • Call Tools | CMake | Unload CMake Project from the main menu.

      the unload cmake option in the main menu

      Upon this action, your project's state is as described in Load CMake.
