CheckOBJCSourceRuns
-------------------
.. versionadded:: 3.16
Check once if given Objective-C source compiles and links into an executable and
can subsequently be run.
.. command:: check_objc_source_runs
.. code-block:: cmake
check_objc_source_runs(<code> <resultVar>)
Check once that the source supplied in ``<code>`` can be built, linked as an
executable, and then run. The ``<code>`` must contain at least a ``main()``
function.
The result is stored in the internal cache variable specified by
``<resultVar>``. If the code builds and runs with exit code ``0``, success is
indicated by boolean ``true``. Failure to build or run is indicated by boolean
``false``, such as an empty string or an error message.
See also :command:`check_source_runs` for a more general command syntax.
The compile and link commands can be influenced by setting any of the
following variables prior to calling ``check_objc_source_runs()``
