DEBUG_CONFIGURATIONS
--------------------

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.
