# CMAKE_<LANG>_FLAGS_INIT

Value used to initialize the `CMAKE_<LANG>_FLAGS` cache entry the first time a build tree is configured for language `<LANG>`. This variable is meant to be set by a `toolchain file`. CMake may prepend or append content to the value based on the environment and target platform.

See also the configuration-specific variables:

- `CMAKE_<LANG>_FLAGS_DEBUG_INIT`
- `CMAKE_<LANG>_FLAGS_RELEASE_INIT`
- `CMAKE_<LANG>_FLAGS_MINSIZEREL_INIT`
