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>``. Success of build and run 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()``
