**Environment**
- Mac M4
- macOS version: [請填]
- LLVM commit: [請填，如有]
**Build Command**
```bash
cmake -G "Unix Makefiles" -DLLVM_ENABLE_PROJECTS="clang;lld;lldb" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=./install ../llvm
```
**Observed error**
```bash
CMake Error at /Users/youzhewei/Desktop/llvm-project/lldb/test/CMakeLists.txt:201 (message):
LLDB test suite requires libc++, but it is currently disabled. Please add
`libcxx` to `LLVM_ENABLE_RUNTIMES` or disable tests via
`LLDB_INCLUDE_TESTS=OFF.
```
**Expectation**
CMake should configure successfully, or at least document proper flags for Mac M4 builds with lldb enabled.
**Steps tried**
• Re-checked cmake flags
• No explicit disabling of libcxx
**Thanks!**
