<pre>
    I was working on LLDB, refactoring some code then randomly got an issue relating to libxml2. I had assume it was because of the patches I've done, but after clone a fresh llvm, i tried compiling again and got the same isssue

**Cmake command:**
```
cmake -G Ninja \
 -DCMAKE_BUILD_TYPE=Release \
  -DLLVM_ENABLE_PROJECTS="clang;lldb" \
 -DCMAKE_C_COMPILER=clang \
  -DCMAKE_CXX_COMPILER=clang++ \
 -DLLVM_TARGET_ARCH=AArch64 \
  -DLLVM_USE_LINKER=lld \
 -DPython3_EXECUTABLE=/Users/juliusalexandre/venv-packaging/bin/python3 \
 -DLLDB_ENFORCE_STRICT_TEST_REQUIREMENTS=ON \
 -DCMAKE_OSX_DEPLOYMENT_TARGET=15.3 \
  -DLLDB_ENABLE_LIBXML2=Off \
 -DLLDB_ENABLE_PYTHON=ON \ -DBUILD_SHARED_LIBS=ON \
  -C ../lldb/cmake/caches/Apple-lldb-macOS.cmake \
 -DLLVM_ENABLE_RUNTIMES="libcxx;libcxxabi;libunwind" \
 ../llvm
```

after running `ninja`:
