I am trying to build Openroad with cmake .. -DGPU=true and I get the following output

Policy CMP0104 is not set: CMAKE_CUDA_ARCHITECTURES now detected for NVCC,
empty CUDA_ARCHITECTURES not allowed. Run "cmake --help-policy CMP0104"

suppress this warning.
CUDA_ARCHITECTURES is empty for target "gpl".
This warning is for project developers. Use -Wno-dev to suppress it.
CMake Error in src/gpl/CMakeLists.txt:
Target "gpl" requires the language dialect "CUDA17" . But the current
compiler "NVIDIA" does not support this, or CMake does not know the flags
to enable it.

I have Cuda installed and on nvidia-smi I get

and on nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2019 NVIDIA Corporation
Built on Sun_Jul_28_19:07:16_PDT_2019
Cuda compilation tools, release 10.1, V10.1.243
Any help on how to get the setup working is really appreciated and thanks in advanced.

Please install a newer version of nvcc and try again. As per NVIDIA docs, you will require at least v11; see more here.

If we bump to cmake 3.10 then https://cmake.org/cmake/help/latest/module/FindCUDA.html suggests we can use the usual VERSION keyword.
FYI - the use of CUDA is quite minimal and probably not worth the bother at this point.
