The CUDA compiler is not able to compile a simple test program

I created a template Clion project in CUDA and it does not seem to work at all.

Clion new projct creation

The only thing which I changed is this line in CMakeLists.txt:

set(CMAKE_CUDA_COMPILER "/usr/local/cuda-10.1/bin/nvcc")

So it looks like this:

cmake_minimum_required(VERSION 3.17)

set(CMAKE_CUDA_COMPILER "/usr/local/cuda-10.1/bin/nvcc")
project(test CUDA)

set(CMAKE_CUDA_STANDARD 14)

add_executable(test main.cu)

set_target_properties(
        test
        PROPERTIES
        CUDA_SEPARABLE_COMPILATION ON)

It does not matter if I try to build the program from Clion or terminal, I always get:

CMake Error at /snap/clion/129/bin/cmake/linux/share/cmake-3.17/Modules/CMakeTestCUDACompiler.cmake:46 (message):
  The CUDA compiler

    "/usr/local/cuda-10.1/bin/nvcc"

  is not able to compile a simple test program.

  It fails with the following output:

I use Ubuntu 20, Clion (2020.2.4) is from the newest snap. I also tried to run it with different versions of gcc and g++ (7, 8 and 9) and CMake (3.17 (snap), 3.18 and 3.19). Additionally:

The path /usr/local/cuda-10.1/bin/nvcc is correct.

It started working when I changed the default system gcc alternative from version 9 to 8. (Ubuntu 20 default gcc version is 9)

sudo update-alternatives --config gcc
