Feature CUDA disabled

[cponder]

What happened?

I'm doing an "vanilla" build using the NVHPC compilers but no special settings.
CUDA is installed under /usr/local/cuda. Is there a setting like

-D CUDA=/usr/local/cuda

that I need to make? I don't see anything about this on the website.

What are the steps to reproduce the bug?

cmake -S ../distro -DCMAKE_INSTALL_PREFIX=/usr/local
make install

Version

1.28.6

Platform (OS and architecture)

Ubuntu 22.04

Relevant log output
