# CUDAFLAGS

New in version 3.8.

This is a CMake Environment Variable. Its initial value is taken from the calling process environment.

Default compilation flags to be used when compiling `CUDA` files. Will only be used by CMake on the first configuration to determine `CUDA` default compilation flags, after which the value for `CUDAFLAGS` is stored in the cache as `CMAKE_CUDA_FLAGS`. For any configuration run (including the first), the environment variable will be ignored if the `CMAKE_CUDA_FLAGS` variable is defined.

See also `CMAKE_CUDA_FLAGS_INIT`.
