ld.lld: error: undefined symbol: mlirModuleGetOperation

I am building with x86_64-windows-gnu target with -DBUILD_SHARED_LIBS=On and -flto=thin. I get mlirModuleGetOperation. What's going on here?

Thanks :)

```

Start by reproducing the x86_64-windows-gnu shared build with ThinLTO from the reported command, then inspect mlir/lib/CAPI/Target/ExportSMTLIB.cpp and the linked MLIR import libraries for mlirModuleGetOperation. Done means identifying the missing linkage or export and completing the failing DLL link successfully.
