Unable to find cuda lib under the names ["cuda", "nvcuda"] in WSL2

[Anivie]

There are some errors when using cudarc in WSL2, and this is because the CUDA environment in WSL is quite special; its default CUDA files are stored in usr/lib/wsl/lib.

Currently, adding /usr/lib/wsl/lib to the LD_LIBRARY_PATH can fix this error.

However, this error shouldn't exist because WSL actually provides this path by default, located in /etc/ld.so.conf.d/ld.wsl.conf, and cudarc does not scan the paths in the files within this directory, which seems to be against convention.
Therefore, please add the paths from the files in this directory to the library search directories to avoid dependency on LD_LIBRARY_PATH.

Now (after the last nvidia package updates from the beginning of November) I have the same on a "regular" Debian 12.
My libcuda is in /usr/lib/x86_64-linux-gnu, where there's a symlink from libcuda.so.1 to libcuda.so.565.57.01.
Adding a symlink from a libcuda.so to libcuda.so.1 fixes the error...

Once I gave up trying to make it work. Your approach works. Thank you.
