 In the `Cppcheck GUI` you have the choice to only analyze a single debug configuration. If you want to use this choice on the command line then create a `Cppcheck GUI` project with this activated and then import the GUI project file on the command line.
 
 To ignore certain folders in the project you can use `-i`. This will skip analysis of source files in the `foo` folder.
