OBJC¶
在 3.16.7 版被加入.
這是一個 CMake 環境變數。其初始值取自呼叫的進程環境。
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.
