Hello,
Just to add one more data point: I have created a new virtual machine from scratch with Windows 10 Pro 64bit, then installed VS 2019 Community Edition with C++ tools, rebooted, installed CUDA 11.3 and CMake 3.20.2.
CMake still detects the CUDA 10.2 toolkit and and does not let me select CUDA 11.3 - I believe there is really something wrong with the CUDA module of CMake as CUDA 10.2 is not present on the system, nor was ever present - in order to make sure of this, I have installed everything from scratch on a fresh Windows VM.
I would be happy to conduct other tests if useful.
Best Regards,
Andrea
