 You can use the following flags with `configure.py`:
 
  * `--system-ocl` -> Don't Download OpenCL deps via cmake but use the system ones
+ * `--no-werror` -> Don't treat warnings as errors when compiling llvm
  * `--cuda` -> use the cuda backend (see [Nvidia CUDA](#build-dpc-toolchain-with-support-for-nvidia-cuda))
  * `--shared-libs` -> Build shared libraries
  * `-t` -> Build type (debug or release)
