+OBJC
+----
+
+.. include:: ENV_VAR.txt
+
+Preferred executable for compiling ``OBJC`` language files. Will only be used
+by CMake on the first configuration to determine ``OBJC`` compiler, after
+which the value for ``OBJC`` is stored in the cache as
+:variable:`CMAKE_OBJC_COMPILER <CMAKE_<LANG>_COMPILER>`. For any configuration
+run (including the first), the environment variable will be ignored if the
+:variable:`CMAKE_OBJC_COMPILER <CMAKE_<LANG>_COMPILER>` variable is defined.
+
+If ``OBJC`` is not defined, the :envvar:`CC` environment variable will
+be checked instead.
