+Subject: [PATCH] [CMake] Use correct exports file for MLIR tools
+
+llvm_add_tool() currently does not respect the passed project and
+puts all tools into LLVMExports.cmake. This means that we end up
+with binaries like mlir-opt in LLVMExports.cmake instead of
+MLIRTargets.cmake, where they should be.
+
+Adjust llvm_add_tool() to take the project into account.
