Ubuntu nvcc致命：不支持的gpu体系结构'；计算30'；

我正在使用这个GitHub回购协议，并遵循它的指示。我在

cmake..

之后得到的错误如下。我该怎么修

我的回答如下：

我有以下几点：

CMake Warning (dev) in CMakeLists.txt:
  No project() command is present.  The top-level CMakeLists.txt file must
  contain a literal, direct call to the project() command.  Add a line of
  code such as

    project(ProjectName)

  near the top of the file, but after cmake_minimum_required().

  CMake is pretending there is a "project(Project)" command on the first
  line.
This warning is for project developers.  Use -Wno-dev to suppress it.

下面是

CMakeLists.txt

文件（我添加了前两行）：

稍后，如果我运行

make

命令，将出现以下错误：

我使用了该代码的第77-83行：

在我的

CMakeLists.txt

文件中：

##set(CUDA_NVCC_FLAGS "${CUDA_NVCC_FLAGS}; -gencode=arch=compute_30,code=sm_30")
##set(CUDA_NVCC_FLAGS "${CUDA_NVCC_FLAGS}; -gencode=arch=compute_30,code=compute_30")

IF ((CUDA_VERSION VERSION_GREATER "10.0") OR (CUDA_VERSION VERSION_EQUAL "10.0"))
    set(CUDA_NVCC_FLAGS "${CUDA_NVCC_FLAGS} -gencode arch=compute_75,code=sm_75")
ENDIF()

IF ((CUDA_VERSION VERSION_GREATER "11.0") OR (CUDA_VERSION VERSION_EQUAL "11.0"))
    set(CUDA_NVCC_FLAGS "${CUDA_NVCC_FLAGS} -gencode arch=compute_80,code=sm_80")
ENDIF()

而且

make

是成功的。显然，忽略在

cmake..

原因是代码很旧，使用的是较旧版本的CUDA，而我的CUDA版本更新得多。
