Building the `gpu` (OpenCL) backend on Windows no longer needs a vendor OpenCL SDK. `cl-sys` links `OpenCL` (#[link(name = "OpenCL")]); instead of requiring an SDK-provided OpenCL.lib, build.rs now generates a vendor-neutral import library at build time from windows/OpenCL.def (all 118 cl-sys exports) — lib.exe for MSVC (located via the cc crate), dlltool for MinGW — and puts it on the link search path. The real OpenCL.dll is supplied at runtime by the GPU driver. build.rs no-ops on non-Windows targets and when the gpu feature is off, and warns rather than panics if the toolchain tool is absent so `cargo check` still works. Combined with the runtime-loaded (dlopen) CUDA/NVML, a Windows build now needs zero external GPU libraries. Add BUILD-windows.md (toolchain, build, crt-static packaging, runtime deps, CI) and link it from the README. Verified the whole crate compiles for x86_64-pc-windows-gnu (default features and gpu,cuda); Linux is unaffected. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
