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.

See the 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 cmake-generator-expressions(7) manual for available expressions. See the cmake-buildsystem(7) manual for more on defining buildsystem properties.
