# OBJC

Added 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.

If `OBJC` is not defined, the `CC` environment variable will be checked instead.
