Description
cuSPARSELt 0.10.0 renamed the DLL in its CUDA 13 Windows wheel from
cusparseLt.dlltocusparseLt_13.dll. Pathfinder currently searches only for the old name, so it cannot load the library from the new wheel and CUDA Python CI fails.Search for
cusparseLt_13.dllfirst, while retainingcusparseLt.dllas a fallback for older installations.The cuSPARSELt 0.10.0 CUDA 13 Linux wheels for both x86-64 and ARM64 still contain
nvidia/cu13/lib/libcusparseLt.so.0. The existing Linux SONAME and search path remain correct, so no Linux change is needed.
