# CMAKE_<LANG>_FLAGS

Flags for all build types.

`<LANG>` flags used regardless of the value of `CMAKE_BUILD_TYPE`.

This is initialized for each language from environment variables:

- `CMAKE_C_FLAGS`: Initialized by the `CFLAGS` environment variable.

- `CMAKE_CXX_FLAGS`: Initialized by the `CXXFLAGS` environment variable.

- `CMAKE_CUDA_FLAGS`: Initialized by the `CUDAFLAGS` environment variable.

- `CMAKE_Fortran_FLAGS`: Initialized by the `FFLAGS` environment variable.
