@raulcd @kou I've investigated this further but I'm stuck on the remaining
linker failure and would appreciate some guidance.
The Windows JNI job now builds almost completely and only fails while
linking `arrow-substrait-substrait-test` with these two unresolved symbols:
- `arrow::engine::internal::CreateScanProjectSubstrait`
- `arrow::engine::internal::CreateScanAggSubstrait`
Both are defined and declared in `test_plan_builder.{cc,h}`
So far I've verified that:
- `test_plan_builder.cc` is included in `ARROW_SUBSTRAIT_SRCS`.
- `arrow_substrait_static` is linked into `arrow-substrait-substrait-test`.
- The linker reports these two symbols as `__declspec(dllimport)`.
- I also investigated `ARROW_ENGINE_STATIC`, but unlike other modules I
couldn't find it being propagated anywhere in the CMake build (it's only
referenced in Meson/pkg-config), so I'm not convinced that's the root cause.
Most other symbols from `arrow_substrait_static` link successfully; only
these two remain unresolved.
At this point I'm not sure where to continue debugging.
