CMAKE_CUDA_HOST_COMPILER should be set before PROJECT (with CUDA language) command but CMAKE_CXX_COMPILER is available after PROJECT command execution.

Once the CUDA language is enabled, the CMAKE_CUDA_HOST_COMPILER variable is read-only and changes to it are undefined behavior.
https://cmake.org/cmake/help/latest/variable/CMAKE_CUDA_HOST_COMPILER.html

And CMake stores path to that default compiler executable in the CMAKE_C_COMPILER variable.

Suggested here way to set custom compiler via two lines

set(CMAKE_CUDA_HOST_COMPILER "${CMAKE_CXX_COMPILER}")
set(CMAKE_CUDA_FLAGS "${CMAKE_CUDA_FLAGS} -ccbin ${CMAKE_CXX_COMPILER}")

results in

nvcc fatal : redefinition of argument 'compiler-bindir'

with old CUDA version. So I believe setting only CMAKE_CUDA_HOST_COMPILER is enough:

This maps to the nvcc -ccbin option.
https://cmake.org/cmake/help/latest/variable/CMAKE_CUDA_HOST_COMPILER.html

docs/Installation-Guide.rst Outdated

The following dependencies should be installed before compilation:

- **CUDA** libraries. Please refer to `this detailed guide`_.
- **CUDA** libraries. Please refer to `this detailed guide`_. Pay great attention to the minimum required versions of host compilers listed in the table from that guide and use only recommended versions of compilers.

I don't think we should re-type this table in our CMakeLists.txt for each supported CUDA version.

I agree! We're likely to make a mistake trying to replicate this all in CMakeLists.txt, and for the limited benefit of raising a more informative error message.

Looks good to me, thanks! By the way I do have a laptop with an NVIDIA graphics card and I've been wanting to learn more about CUDA, so if there are ever small tasks I can help on please feel free to assign them to me. My primary focus for the near future will be on the Dask module, but happy to help with the CUDA stuff wherever I can.

@jameslamb Thank you very much! I think you can start from investigating why Dask works(?) fine on CUDA but fails on OpenCL.
