Specify the buildsystem variant to use.
See the :variable:`CMAKE_XCODE_BUILD_SYSTEM` variable for allowed values.
For example, to select the original build system under Xcode 12,
run :manual:`cmake(1)` with the option ``-T buildsystem=1``.

xcode-12-new-build-system
-------------------------
* The :generator:`Xcode` generator now uses the Xcode "new build system"
when generating for Xcode 12.0 or higher.
See the :variable:`CMAKE_XCODE_BUILD_SYSTEM` variable.
One may use ``-T buildsystem=1`` to switch to the legacy build system.

``1``
The original Xcode build system.
This is the default.
This is the default when using Xcode 11.x or below.
``12``
The Xcode "new build system" introduced by Xcode 10.
It became mature enough for use by CMake in Xcode 12.
This is the default when using Xcode 12.x or above.
The ``CMAKE_XCODE_BUILD_SYSTEM`` variable is informational and should not
