CheckOBJCCompilerFlag
|
|
---------------------
|
|
|
|
.. versionadded:: 3.16
|
|
|
|
Check whether the Objective-C compiler supports a given flag.
|
|
|
|
.. command:: check_objc_compiler_flag
|
|
|
|
.. code-block:: cmake
|
|
|
|
check_objc_compiler_flag(<flag> <resultVar>)
|
|
|
|
Check that the ``<flag>`` is accepted by the compiler without
|
|
a diagnostic. Stores the result in an internal cache entry
|
|
named ``<resultVar>``.
|
|
|
|
A positive result from this check indicates only that the compiler did not
|
|
issue a diagnostic message when given the flag. Whether the flag has any
|
|
effect or even a specific one is beyond the scope of this module.
|
|
|
|
The check is only performed once, with the result cached in the variable named
|
|
by ``<resultVar>``. Every subsequent CMake run will reuse this cached value
|
|
rather than performing the check again, even if the ``<code>`` changes. In
|
|
order to force the check to be re-evaluated, the variable named by
|
|
``<resultVar>`` must be manually removed from the cache.
|
|
|
|
The compile and link commands can be influenced by setting any of the
|
|
following variables prior to calling ``check_objc_compiler_flag()``
