I'm following https://mlir.llvm.org/getting_started/ to get a build of MLIR on my Mac. I used clang-15 as my compiler, and ran
```
cmake -G Ninja ../llvm \
-DLLVM_ENABLE_PROJECTS=mlir \
-DLLVM_BUILD_EXAMPLES=ON \
-DLLVM_TARGETS_TO_BUILD="X86" \
-DCMAKE_BUILD_TYPE=Release \
-DLLVM_ENABLE_ASSERTIONS=ON \
-DLLVM_CCACHE_BUILD=ON \
-DCMAKE_C_COMPILER=clang \
-DCMAKE_CXX_COMPILER=clang++
cmake --build . --target check-mlir
```
I saw the following error that `_libcpp_verbose_abort` was undefined. Based on the comments on https://libcxx.llvm.org/UsingLibcxx.html I guessed to remove the assertions flag of the build which has gotten me past this point of the build.
```
➜ build git:(main) cmake --build . --target check-mlir (base) 14:02:32
