depend on libnvjitlink-dev at build time unconditionally

[jameslamb]

rapidsai/cuvs#1923 switched cuVS to always enabling JIT+LTO, and therefore requiring nvJitLink at build and runtime.

Previously, it had only been required for CUDA 13.

cuGraph pulls cuVS via CPM and builds it from source, but wasn't updated to match, resulting in CUDA 12 builds here failing like this:

 │ │ CMake Error at build/_deps/cuvs-src/cpp/CMakeLists.txt:754 (target_link_libraries):
 │ │   Target "cuvs" links to:
 │ │     CUDA::nvJitLink
 │ │   but the target was not found.  Possible reasons include:
 │ │     * There is a typo in the target name.
 │ │     * A find_package call is missing for an IMPORTED target.
 │ │     * An ALIAS target is missing.
 │ │ CMake Error at build/_deps/cuvs-src/cpp/CMakeLists.txt:812 (target_link_libraries):
 │ │   Target "cuvs_static" links to:
 │ │     CUDA::nvJitLink
 │ │   but the target was not found.  Possible reasons include:
 │ │     * There is a typo in the target name.
 │ │     * A find_package call is missing for an IMPORTED target.
 │ │     * An ALIAS target is missing.

(example build link)

This resolves that, by removing "if CUDA 13" types of guards around this project's libnvJitLink dependency.

Notes for Reviewers

Some builds may still fail here

Like this:

  /__w/cugraph/cugraph/python/libcugraph/build/py3-none-linux_aarch64/_deps/cccl-src/lib/cmake/cub/../../../cub/cub/device/dispatch/kernels/kernel_scan_warpspeed.cuh(455): error: more than one instance of function template "cub::detail::scan::warpReduce" matches the argument list:
              function template "T raft::warpReduce(T, ReduceLambda)" (declared at line 49 of /pyenv/versions/3.14.3/lib/python3.14/site-packages/libraft/include/raft/util/reduction.cuh)
              function template "Tp cub::detail::scan::warpReduce(Tp, ScanOpT &)" (declared at line 247)
              argument types are: (unsigned int, raft::add_op)
     regWarpSum = warpReduce(regThreadSum, scan_op);

Until rapidsai/cuvs#1954 is resolved, which @viclafargue is working on in rapidsai/cuvs#1963

[jameslamb]

Now that rapidsai/cuvs#1963 is merged, pushed an empty commit to re-run all CI. Hopefully we will see builds pass here now.

All wheel tests are failing like this:

ImportError while loading conftest '/__w/cugraph/cugraph/python/pylibcugraph/pylibcugraph/tests/conftest.py'.
python/pylibcugraph/pylibcugraph/tests/conftest.py:10: in <module>
    from pylibcugraph.testing import utils
/pyenv/versions/3.11.15/lib/python3.11/site-packages/pylibcugraph/__init__.py:15: in <module>
    import pylibcugraph.comms

    from .comms_wrapper import init_subcomms
E   ImportError: libcugraph.so: cannot open shared object file: No such file or directory

(build link)

Just seeing that it's in .comms, I strongly suspect this is because there haven't been new nightly libraft / raft-dask wheels published in a while, and there have been ABI breaks in RMM since the last time they were published.

I'll go get some new raft wheels published.

[jameslamb]

Once rapidsai/raft#2991 is merged (or any other RAFT PR, if another gets there sooner) and there are new nightly packages, I'll restart CI here.

[jameslamb]

New RAFT build finished (https://github.com/rapidsai/raft/actions/runs/23807692461/job/69387358843), just pushed a commit restarting CI here. This PR is already queued to auto-merge, so if CI passes it'll merge in and things should be working in this repo again.
