Help/envvar/OBJC.rst
.. versionadded:: 3.16.7
.. include:: include/ENV_VAR.rst
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.
