FOLDER

For IDEs that present targets using a folder hierarchy, this property specifies the name of the folder to place the target under. To nest folders, use FOLDER values such as GUI/Dialogs with / characters separating folder levels. Targets with no FOLDER property will appear as top level entities. Targets with the same FOLDER property value will appear in the same folder as siblings.

Only some CMake generators honor the FOLDER property (e.g. Xcode or any of the Visual Studio generators). Those generators that don't will simply ignore it.

This property is initialized by the value of the variable CMAKE_FOLDER if it is set when a target is created.

The global property USE_FOLDERS must be set to true, otherwise the FOLDER property is ignored.
