Minor comments.
Thanks for tackling this one!

I checked that cusparselt builds

[prusnak]

I am trying to build torch-2.6.0 from #377785 on top of this PR using the following patch (I also tried cusparselt instead of cusparselt.lib):

diff --git a/pkgs/development/python-modules/torch/default.nix b/pkgs/development/python-modules/torch/default.nix

+        cusparselt.lib
         libcublas

but the following error still persist:

error: auto-patchelf could not satisfy dependency libcusparseLt.so.0 wanted by /nix/store/90xjhvjdbli1b0vcqcq6if9hr2qgkvpp-python3.12-torch-2.6.0/lib/python3.12/site-packages/torch/lib/libtorch_cuda.so

The file does exists on my machine:

$ ls /nix/store/0fxpjwfi41vrsh2qd5c30g018kdffzld-libcusparse_lt-0.7.1.0-lib/lib/
libcusparseLt.so  libcusparseLt.so.0  libcusparseLt.so.0.7.1.0

However it is in "${cusparselt.lib}/lib" instead of "${cusparselt.lib}/lib64", not sure if this is relevant

@GaetanLepage do we need to patch something in cusparselt (this PR) or it is something to be fixed in torch (PR #377785)?

This is a good question... @SomeoneSerge will probably know.

Let's merge this and fix in the subsequent PR if needed.
