Manage CMake Project Files
Add new files
In the Project tree, right-click the folder you want to add a file into and select New from the context menu. Choose the desired file type:
Specify the name, type, and additional options for the new file.
For C++ Class, C/C++ Source, and C/C++ Header file templates, CLion will prompt you to add the new file to one or several existing CMake targets:
If you have selected the target on the previous step, the new entry will be automatically added to CMakeLists.txt:
Manage included files
When you include a header or source file located under the project root into any project file, CLion treats it as a project file as well. There is no need to list such includes manually in CMakeLists.txt.
Add non-included files
When a source or header file is not included in any of the project files or CMake targets, CLion notifies you about it:
In this case, you need to specify the file as a project one manually. Use one of the following approaches depending on the file location:
If the file is located under the project root, add it to a target using
add_library()command. For example:
Beforeadd_executable (TestProject main.cpp)
Afteradd_executable (TestProject main.cpp new_file.cpp)
When the directory that contains non-project sources is located under the project root, you can also mark it as library: right-click in the Project view and select from the context menu.
To use library files located outside the project root, you need to specify header search paths so that CLion can index the directories and provide completion and navigation for the

Upon any of these actions, CLion will prompt you to reload the project (when automatic reload is disabled):
