c++ - CLion 没有正确检测到作为 CUDA 编译器的 clang

Question

我将 CMake 3.18 与 CLion 2020.2.5 一起使用，并希望将 Clang 用作 CUDA 编译器。我在我的顶部使用以下两行来做到这一点CMakeLists.txt：

set(CMAKE_CUDA_COMPILER_ID Clang)
set(CMAKE_CUDA_COMPILER ${CMAKE_CXX_COMPILER})

它对代码非常有效，而且我也 CLion 似乎能够很好地处理代码。但是在配置项目的时候还是会报错：

-- Configuring done
-- Generating done
-- Build files have been written to: /home/mu/project

Problems were encountered while collecting compiler information:
    Unexpected compiler output. This compiler might be unsupported.
    If you are using GCC/Clang, please report the bug in https://youtrack.jetbrains.com/issues/CPP.

在错误日志中，我发现：

Checking whether the CUDA compiler is NVIDIA using "" did not match "nvcc: NVIDIA \(R\) Cuda compiler driver":
clang version 11.0.0 (Fedora 11.0.0-2.fc33)
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: /usr/bin

在输出日志中，它似乎可以很好地识别编译器：

Compilation of the CUDA compiler identification source "CMakeCUDACompilerId.cu" produced "a.out"

The CUDA compiler identification is Clang, found in "/home/mu/project/CMakeFiles/3.18.4/CompilerIdCUDA/a.out"

如何解决 CMake 和 CLion 之间的问题？
