New in version 3.16.7.
This is a CMake Environment Variable. Its initial value is taken from the calling process environment.
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 CMAKE_OBJC_COMPILER. For any configuration run (including the first), the environment variable will be ignored if the CMAKE_OBJC_COMPILER variable is defined.
OBJC is not defined, the CC environment variable will be checked instead.
