OBJCXXFLAGS

在 3.16 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。

Add default compilation flags to be used when compiling Objective C++ (.mm) files.

CMake uses this environment variable value, in combination with its own builtin default flags for the toolchain, to initialize and store the CMAKE_OBJCXX_FLAGS cache entry. This occurs the first time a build tree is configured for language OBJCXX. For any configuration run (including the first), the environment variable will be ignored if the CMAKE_OBJCXX_FLAGS variable is already defined.

See also CMAKE_OBJCXX_FLAGS_INIT.
