| ALLOW_DUPLICATE_CUSTOM_TARGETS |
| ------------------------------ |
| |
| Allow duplicate custom targets to be created. |
| |
| Normally CMake requires that all targets built in a project have |
| globally unique logical names (see policy :policy:`CMP0002`). |
| This is necessary to generate meaningful project file names in |
| :generator:`Xcode` and :ref:`Visual Studio Generators` IDE |
| generators. 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. |
