Specify which configurations are for debugging.

The value must be a semi-colon separated list of configuration names. Currently this property is used only by the target_link_libraries command (see its documentation for details). Additional uses may be defined in the future.

This property must be set at the top level of the project and before the first target_link_libraries command invocation. If any entry in the list does not match a valid configuration for the project the behavior is undefined.
