Open and Reopen Projects
In CLion, you can open several projects simultaneously in different windows. By default, each time you open a project while another one is opened, CLion prompts you to choose whether to open the project in the same window or in a new window. If necessary, you can change this behavior using controls on the System Settings page.
In the Project Opening section of the System Settings page, choose one of the following options:
Open project in a new window to open a new CLion window each time a new project is opened.
Open project in the same window to stay in the same CLion window.
Confirm window to open project in to keep the default behavior and display a dialog box to choose how to open each new project.
Opening projects
Open a project
Click Open on the Welcome screen or on the main menu.
-
In the Select Path dialog, select the directory that contains the project to open.
In case of a CMake project, the directory should contain CMakeLists.txt. For a compilation database project, it should contain compile_commands.json. For a gradle project, you need to point CLion to the build.gradle file and then choose Open as Project.
Specify whether you want to open the project in a new frame, or close the current project and reuse the existing frame.
Open a project from the command line
In the command prompt, type:
<CLion> <path_to_the_project folder>See Opening Files from Command Line for more information.
