It also allows the target names to be referenced +unambiguously. + +Makefile generators are capable of supporting duplicate :command:`add_custom_target` +names. For projects that care only about :ref:`Makefile Generators` and do +not wish to support :generator:`Xcode` or :ref:`Visual Studio Generators` IDE +generators, one may set this property to ``True`` +to allow duplicate custom targets. The property +allows multiple :command:`add_custom_target` command calls in different +directories to specify the same target name. However, setting this +property will cause non-Makefile generators to produce an error and +refuse to generate the project. |
