Start CUDA Debugging greyed out in cmake project on VS2022

Development Tools Nsight Visual Studio Edition
#1

I’m struggling in debugging a CUDA code within a cmake project on VS2022. Specifically, I open a cmake project in VS2022 and build it with ‘-G’ nvcc flag. But I can’t debug into the kernel code. Meanwhile I can’t click “Start CUDA Debugging” in “Extension->Nsight” because it greyed out.

My toy cmake project only contain a hello.cu and a CMakeLists.txt.

cmake_minimum_required(VERSION 3.18 FATAL_ERROR)
project(hello LANGUAGES CUDA)
add_executable(hello hello.cu)
target_compile_options(hello PRIVATE $<$<COMPILE_LANGUAGE:CUDA>:-G>)

VisualStudio 2022; Nsight 2022; CUDA Toolkit 11.7

#2

Faced same issue with same setup. Additionally, i had created VS project based on MSBuild with (cuda snippet) and got debug toolchain available, but, ‘Start CUDA Debugging (nextgen)’ led to endless waiting for a breakpoint. After manual stop debug launch button was no longer enabled.

@michael.ky I am facing a similar issue and using a VS-based project does not help:
