我的项目使用CMake-GUI和visual studio。我的系统上没有安装gpu卡。生成的visual studio解决方案将nvcc标志设置为compute_30和sm_30,但我需要将其设置为compute_50和sm_50。
我使用CMake 3.10.1和Visual Studio 14 2015进行64位编译。
我希望取代CMake的默认设置。我没有使用Find CUDA方法来搜索和添加CUDA。我在CMAKE中添加了CUDA作为语言支持,而VS则基于此实现了CUDA Build定制。

有了CMake 3.18,就有了新的目标属性CUDA_ARCHITECTURES
。从文档here:
set_property(TARGET myTarget PROPERTY CUDA_ARCHITECTURES 35 50 72)
为真实和虚拟体系结构30、50和72生成代码。
set_property(TARGET myTarget PROPERTY CUDA_ARCHITECTURES 70-real 72-virtual)
生成用于实际架构70和虚拟架构72的代码。

正确的方法是:
target_compile_options(myTarget PRIVATE $<$<COMPILE_LANGUAGE:CUDA>:-gencode arch=compute_50,code=sm_50>)
根据需要选择“ PRIVATE / PUBLIC”。这是设置每个目标标志的正确方法。

所以我能够自己解决这个问题。我们可以通过以下方式设置它 -
string(APPEND CMAKE_CUDA_FLAGS“-gencode arch = compute_50,code = sm_50”)

我webpack.config.js默认获取(和使用)第一个已安装的物理设备的计算机功能设置,但可以通过设置CUDA_SM环境变量来覆盖。这是模块(将内容放在.cmake
文件中并将其放在包含的文件夹中):
# This module determines which compute capability / SM version
# we should be compiling our CUDA code for, and adds the appropriate
# switch to the NVCC compiler flags - so that you don't have to worry
# about it.
#
# TODO: Be willing to take CUDA_CC, CUDA_TARGET_COMPUTE_CAPABILITY,
# CUDA_TARGET_COMPUTE or CUDA_TARGET_COMPUTE_CAP and maybe even
# those without the CUDA_ prefix
if (NOT CUDA_TARGET_COMPUTE_CAPABILITY)
