The standalone example's pyproject.toml declares `dynamic = ["version"]` but does not configure a `tool.scikit-build metadata.version.provider`. Newer versions of scikit-build-core reject this combination with: ``` AssertionError: project.version is not specified, must be statically present or tool.scikit-build metadata.version.provider configured when dynamic ``` Just pin a static placeholder version instead of adding a "provider".

An out-of-tree MLIR dialect
This is an example of an out-of-tree MLIR dialect along with a standalone opt-like tool to operate on that dialect.
Building - Component Build
This setup assumes that you have built LLVM and MLIR in $BUILD_DIR and installed them to $PREFIX. To build and launch the tests, run
mkdir build && cd build
cmake -G Ninja .. -DMLIR_DIR=$PREFIX/lib/cmake/mlir -DLLVM_EXTERNAL_LIT=$BUILD_DIR/bin/llvm-lit
cmake --build . --target check-standalone
To build the documentation from the TableGen description of the dialect operations, run
cmake --build . --target mlir-doc
Note: Make sure to pass -DLLVM_INSTALL_UTILS=ON when building LLVM with CMake in order to install FileCheck to the chosen installation prefix.
Building - Monolithic Build
This setup assumes that you build the project as part of a monolithic LLVM build via the LLVM_EXTERNAL_PROJECTS mechanism.
To build LLVM, MLIR, the example and launch the tests run
mkdir build && cd build
cmake -G Ninja `$LLVM_SRC_DIR/llvm` \
-DCMAKE_BUILD_TYPE=Release \
-DLLVM_TARGETS_TO_BUILD=host \
-DLLVM_ENABLE_PROJECTS=mlir \
-DLLVM_EXTERNAL_PROJECTS=standalone-dialect -DLLVM_EXTERNAL_STANDALONE_DIALECT_SOURCE_DIR=../
cmake --build . --target check-standalone
Here, $LLVM_SRC_DIR needs to point to the root of the monorepo.
