CUDA编译期间，CLion的目标卸载过程中使用了错误的编译器

我正在尝试在CLion 2020.1中配置一个非常简单的CUDA项目。

我使用的是Fedora 31（默认gcc为9.3），但是从源代码编译了gcc 8.2才能与Cuda Toolkit 10.2一起使用。

Cuda示例使用所提供的make进行编译并运行良好，因此编译器可以在nvcc上正常工作并正常运行。

在CLion中，我已经用柯南下载了googletest。“柯南”配置文件将8.2指定为要使用的gcc版本。

CMakeOutput.log中对GCC的所有引用均指向正确的bin文件。但是，由于使用了错误的版本，所以我不断收到编译器错误。

在我的CMakeLists.txt中，我有：

set(gcc82 /usr/local/gcc82/bin)
set(CMAKE_C_COMPILER ${gcc82}/gcc82)
set(CMAKE_CXX_COMPILER ${gcc82}/g++82)
set(CMAKE_CUDA_HOST_COMPILER ${gcc82}/g++82)

project(RBF-Interpolation-Tests CUDA CXX)

CMake配置步骤似乎也很高兴：

尽管在我的机器上可以使用CLion，但该版本是最新的：

我总是得到的错误是：

这绝对是错误的GCC版本。

我尝试过在Settings-> Cmake-> Environment withCC=/usr/local/gcc82/bin;CXX=/usr/local/gcc82/bin/g++82中以及在Settings-> Toolchains-> C和C ++ Compiler中指定GCC版本，结果是相同的。

我不知道为什么目标卸载过程没有选择指定的gcc版本。有任何想法吗？
