I have two projects and one of them is already in the project's tree of the workspace. I tried to import the second one into the workspace as follows: File --> Import project (Selecting the project I want to import) and then there's an Import project dialog asks me to choose one of the following options:
Directory _project_dir__ contains CMakeLists.txt
Open project, Overwrite CMakeLists.txt and Cancel.
I chose Open project.
Then the following's being appeared: New projects can either be opened in a new window or replace the project in the existing window. How would you like to open the project?
So, I presume there's no way to add multiple projects in the same workspace? If so, couldn't you explain why did you do so?
