This issue is bizarre and I have no idea why it’s happening. I’m trying to compile ArrayFire from source, using vcpkg to find all the dependencies. I’ve installed all the required dependencies, and have a CUDA toolkit with visual studio integration.
From the output below, you can see that it correctly identifies the compiler as nvcc.exe
CMake Error at C:/Program Files/CMake/share/cmake-3.25/Modules/CMakeDetermineCompilerId.cmake:739 (message):
Compiling the CUDA compiler identification source file
"CMakeCUDACompilerId.cu" failed.
Compiler: C:/Program Files/NVIDIA GPU Computing
Toolkit/CUDA/v12.3/bin/nvcc.exe
Build flags:
Id flags: --keep;--keep-dir;tmp -v
But then later it uses the Microsoft c++ compiler for some reason.

The vcpkg manifest was disabled, but we found a manifest file in C:\Users\kivik\Desktop\project\external\arrayfire\. You may want to enable vcpkg manifests in your properties page or pass /p:VcpkgEnableManifest=true to the msbuild invocation.

I’ve set the tool chain as expected in my user presets file:
"CMAKE_TOOLCHAIN_FILE": "C:/vcpkg/scripts/buildsystems/vcpkg.cmake"
I’ve tried setting several different variables, one after another (not all at the same time) for CUDA:
"CMAKE_VS_PLATFORM_TOOLSET_CUDA_CUSTOM_DIR": "C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v12.3"
"CMAKE_VS_PLATFORM_TOOLSET_CUDA_DIR": "C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v12.3"
"CUDA": "C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v12.3"
"CMAKE_CUDA_COMPILER": "C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v12.3/bin/nvcc.exe"
But I don’t think that is the issue here, because it is finding the CUDA compiler. I think there’s something else going on, I just don’t know what. I’m not building it in the Visual Studio IDE, I’m trying to configure it using powershell and CMake.
My cmake version is 3.25.2.
CUDA is 12.3.

The lib directory in my CUDA toolkit has a x64 subdirectory, so it should be x64 compatible.
In the CMakeFiles, the CompilerIdCUDA.vcxproj file contains:

If someone can make sense of this, I’d really appreciate it.
