Add more directories to the "Project Viewer"

My folder tree is

-- root

---- .git

---- SourceFiles

---- BuildOutput

---- Artifacts

The cmake is outputting to BuildOutput, but the cmakelist root is in SourceFiles, so what I see in "Project View" on the left pane is only the SourceFiles.

I want to show also BuildOutput directory and Artifacts directory (outputs from `install` commands)

Thank you
