🧾 Docs - Integrate generated MLIR dialect docs into our docs site

[burgholzer]

Background

CMake uses add_mlir_doc(...) to generate dialect and interface docs, but they aren’t surfaced in our docs site yet.

Problem

Users can’t easily find dialect/op/interface documentation.

Proposal:

• Update CMake/docs to copy or build generated docs into docs/_build (or Sphinx sources), and link them from docs/mlir.md.

Examples:

add_mlir_doc(MQTRefOps MLIRMQTRefDialect Dialects/ -gen-dialect-doc)
add_mlir_doc(MQTRefInterfaces MLIRMQTRefInterfaces Dialects/ -gen-op-interface-docs)

Acceptance criteria:

• Generated artifacts included in published docs; navigation links present.
