Standalone mlir project

MLIR

I was trying to make MLIR’s toy tutorial a standalone project, but I got an error in cmake. This is my error message

With the directory layout as you have it, you should move this into a CMakeLists.txt in the mlir directory. LLVM rules that add libraries check their current directory to verify that all cpp sources were included (intending one library per directory). You can override this by adding PARTIAL_SOURCES_INTENDED to the add_*_library but it is better to comply with the directory structure the project likes.

Thank you for your reply. I did not choose to build Example when build the LLVM project. So I don’t include example in my LLVM and MLIR library. Because the LLVM project is huge and takes too long to compile, I don’t want to compile it all again. I am now copying CMakeLists.txt in MLIR and it works normally now
