CUDA build fails with GCC 12

[jcelerier]

Here's the error:

I have the same issue

Use GCC 11 instead.

To install GCC 11 on arch linux:

pacman -S gcc11

Then, remove any prior build directories and before running cmake again, set GCC 11 as your compiler:

export CC=gcc-11; export CXX=g++-11

Then you should be able to build without issues.
