There are many different versions of the `cudatoolkit` and related
cuda packages, and it can be tricky to ensure they remain compatible.
- `cudaPackages` is now a package set with `cudatoolkit`, `cudnn`, `cutensor`, `nccl`, as well as `cudatoolkit` split into smaller packages ("redist");
- expressions should now use `cudaPackages` as parameter instead of the individual cuda packages;
- `makeScope` is now used, so it is possible to use `.overrideScope'` to set e.g. a different `cudnn` version;
- `release-cuda.nix` is introduced to easily evaluate cuda packages using hydra.
I currently do not have much time to work on nixpkgs. Remove
myself as a maintainer from a bunch of packages to avoid that
people are waiting on me for a review.
The libtorch CMake files are in the `dev` output and used relative
paths to locate the shared libraries. This fails, because the
libraries are in the `out` output. This change patches the CMake files
to use library paths from `out`.
See #102146.
- Make passthru.tests an attrset.
- Remove CMake VERBOSE option.
- Remove spurious `cat CMakeLists.txt`.
- Run the test as well.
- Actually test some functionality.
