    Problem:
- Trying to install MLIR from https://mlir.llvm.org/getting_started/, but using "Unix Makefiles" for build instead of Ninja
- CMake generate step fails due to 
`Imported target "ZLIB::ZLIB" includes non-existent path
"/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.3.sdk/usr/include"`
- Recently updated my version of XCode, so path in CMake file should be `/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.3.sdk`

Notes:
- LLVM was installed using Unix Makefiles
- My command:
`cmake -G "Unix Makefiles" ../llvm    -DLLVM_ENABLE_PROJECTS=mlir -DLLVM_BUILD_EXAMPLES=ON    -DLLVM_TARGETS_TO_BUILD="Native;NVPTX;AMDGPU" -DCMAKE_BUILD_TYPE=Release    -DLLVM_ENABLE_ASSERTIONS=ON`

Attempted Solution
- Tried adding the flag 
`DCMAKE_OSX_SYSROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.3.sdk` (still same result as image)
