When issuing this command: `cmake -B build-Xcode -G "Xcode" -S llvm -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra;mlir" -DCMAKE_BUILD_TYPE=Debug -DLLVM_ENABLE_ASSERTIONS=OFF -DCMAKE_OSX_SYSROOT=$(xcrun --sdk macosx --show-sdk-path)`
I get this error:
```
CMake Error in /path/to/llvm-project/mlir/include/mlir/Dialect/Arith/IR/CMakeLists.txt:
The custom command generating
/path/to/llvm-project/build-Xcode/tools/mlir/include/mlir/Dialect/Arith/IR/ArithOpsEnums.h.inc
is attached to multiple targets:
MLIRArithOpsIncGen
MLIRArithOpsInterfacesIncGen
but none of these is a common dependency of the other(s). This is not
allowed by the Xcode "new build system".
```
Removing "mlir" from -DLLVM_ENABLE_PROJECTS allows CMake to proceed successfully. This is with CMake version 3.31.7.
