# CMAKE_XCODE_ATTRIBUTE_<an-attribute>

Added in version 3.1.

Set Xcode target attributes directly.

Tell the `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 `XCODE_ATTRIBUTE_<an-attribute>` target property to set attributes on a specific target.

Contents of `CMAKE_XCODE_ATTRIBUTE_<an-attribute>` may use "generator expressions" with the syntax `$<...>`. See the `cmake-generator-expressions(7)` manual for available expressions. See the `cmake-buildsystem(7)` manual for more on defining buildsystem properties.
