Cannot build for Windows 11 (cudaplot)

[MarcoBonino]

I'm on current head: 84f5133

I'm trying to build from Windows 11 (26100.3624), with Intel i9 14900KF cpu.
Using cmake version 4.0.0, all compiler and cuda version in the log.

After clean clone (from git-bash):

mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release

I get the following error:

$ cmake .. -DCMAKE_BUILD_TYPE=Release

Could someone help ?
Thanks!

Do you have the Cuda Toolkit itself installed (not just drivers)?
https://developer.nvidia.com/cuda-downloads

Looks like you do. In some instances to make CMake happy you had to specify manually the path to the toolkit or nvcc. I don't recall what these variable names were. But you might be able to find it searching online. (They are set at configuration time: cmake -DSOME_CUDA_VAR=...)
