BUILDSYSTEM_TARGETS

New in version 3.7.

This read-only directory property contains a semicolon-separated list of buildsystem targets added in the directory by calls to the add_library(), add_executable(), and add_custom_target() commands. The list does not include any Imported Targets or Alias Targets, but does include Interface Libraries. Each entry in the list is the logical name of a target, suitable to pass to the get_property() command TARGET option.
