XCODE_ATTRIBUTE_<an-attribute> ------------------------------ Set Xcode target attributes directly. Tell the :generator:`Xcode` generator to set ``<an-attribute>`` to a given value in the generated Xcode project. Ignored on other generators. This offers low-level control over the generated Xcode project file. It is meant as a last resort for specifying settings that CMake does not otherwise have a way to control. Although this can override a setting CMake normally produces on its own, doing so bypasses CMake's model of the project and can break things. See the :variable:`CMAKE_XCODE_ATTRIBUTE_<an-attribute>` variable to set attributes on all targets in a directory tree. Contents of ``XCODE_ATTRIBUTE_<an-attribute>`` may use "generator expressions" with the syntax ``$<...>``. See the :manual:`cmake-generator-expressions(7)` manual for available expressions. See the :manual:`cmake-buildsystem(7)` manual for more on defining buildsystem properties.
