CMake找不到CUDA：“找不到cmake模块文件：CMakeDetermineCUDACompiler.cmake”。 [英] CMake cannot find CUDA: "Could not find cmake module file: CMakeDetermineCUDACompiler.cmake"

问题描述

我正在尝试编写需要cuda功能的CMake文件。咨询​​此答案，我将此行添加到了CMakeLists.txt：

I'm trying to write a CMake file which needs cuda functionalities. Consulting this answer, I added this line to my CMakeLists.txt:

set(CMAKE_CUDA_COMPILER  /usr/local/cuda-9.2/bin/nvcc)

但是使用 cmake 命令时仍然抱怨：

But when using cmake command it still complains:

yuqiong@yuqiong-G7-7588:/media/yuqiong/DATA/alexnet/src/cpp/train$ cmake .
CMake Error: Could not find cmake module file: CMakeDetermineCUDACompiler.cmake
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:
CMAKE_CUDA_COMPILER_ENV_VAR
CMake Error: Could not find cmake module file: /media/yuqiong/DATA/alexnet/src/cpp/train/CMakeFiles/3.5.1/CMakeCUDACompiler.cmake
CMake Error: Could not find cmake module file: CMakeCUDAInformation.cmake
CMake Error: Could not find cmake module file: CMakeTestCUDACompiler.cmake
-- Configuring incomplete, errors occurred!
See also "/media/yuqiong/DATA/alexnet/src/cpp/train/CMakeFiles/CMakeOutput.log".

这似乎令人困惑，因为我不知道在哪里还要设置环境变量？知道为什么 set 命令不能帮助cmake查找nvcc编译器吗？

Which seems confusing, as I don't know where else to set the environment variable? Any idea why the set command does not help cmake find the nvcc compiler?

以防万一，这里是我的 CMakeLists.txt ：

Just in case helpful, here is my CMakeLists.txt:

cmake_minimum_required(VERSION 3.5.1)
set(CMAKE_CUDA_COMPILER  /usr/local/cuda-9.2/bin/nvcc)

project(train LANGUAGES CXX CUDA)

set(CMAKE_CXX_STANDARD 14)
find_package( OpenCV REQUIRED )
include_directories( ${OpenCV_INCLUDE_DIRS} )


add_executable(train train.cu)
target_link_libraries( train ${OpenCV_LIBS} )

推荐答案

实际上，您需要在Linux上使用CMake 3.8才能使用 project（train LANGUAGES CUDA）。以前，您需要使用以下旧方法：

Actually, you need CMake 3.8 on Linux to use project(train LANGUAGES CUDA). Before, you need the old way with:

FindPackage(CUDA)

并手动添加库。

失败是因为您的CUDA没有本机支持CMake版本，请使用旧方法。

The failure is because there is no native support for CUDA in your CMake version, use the old method.
