An out-of-tree MLIR dialect

This is an example of an out-of-tree MLIR project, using the Ch1 of the MLIR tutorial.

Building

This setup assumes that you have built LLVM and MLIR in $LLVM_BUILD_DIR and installed them to $LLVM_INSTALL_PREFIX. To build, run

mkdir build && cd build
cmake -G Ninja .. -DMLIR_DIR=$LLVM_INSTALL_PREFIX/lib/cmake/mlir -DLLVM_EXTERNAL_LIT=$LLVM_BUILD_DIR/bin/llvm-lit
cmake --build .

Note: Make sure to pass -DLLVM_INSTALL_UTILS=ON when building LLVM with CMake in order to install FileCheck to the chosen installation prefix.
