I did install MLIR, along with LLVM. Here is my installation location

You need to set MLIR_DIR to the directory containing the MLIRConfig.cmake, apparently in your case:

set(MLIR_DIR /usr/local/llvm/lib/cmake/mlir)

Iā€™d also highly recommend using something close to HEAD, if at all possible. :slight_smile:
