"No thread API"

Hi, I just downloaded 0.11.2 on an Intel Mac, MacOS Ventura 13.1

In both trying to compile examples as with my own older apps I run into the following error: “No thread API”, triggered by a __config, which claims to be a ‘part of the LLVM Project’.

The segment that triggered the error looks like this:

// Thread API
#if !defined(_LIBCPP_HAS_NO_THREADS) && \
    !defined(_LIBCPP_HAS_THREAD_API_PTHREAD) && \
    !defined(_LIBCPP_HAS_THREAD_API_WIN32) && \
    !defined(_LIBCPP_HAS_THREAD_API_EXTERNAL)
#  if defined(__FreeBSD__) || \
      defined(__wasi__) || \
      defined(__NetBSD__) || \
      defined(__OpenBSD__) || \
      defined(__NuttX__) || \
      defined(__linux__) || \
      defined(__GNU__) || \
      (defined(__APPLE__) && !defined(_LIBCPP_ON_RTKIT)) || \
      defined(__sun__) || \
      defined(__MVS__) || \
      defined(_AIX)
#    define _LIBCPP_HAS_THREAD_API_PTHREAD
#  elif defined(_LIBCPP_ON_RTKIT)
#    define _LIBCPP_HAS_THREAD_API_C11
#  elif defined(__Fuchsia__)
     // TODO(44575): Switch to C11 thread API when possible.
#    define _LIBCPP_HAS_THREAD_API_PTHREAD
#  elif defined(_LIBCPP_WIN32API)
#    define _LIBCPP_HAS_THREAD_API_WIN32
#  else
#    error "No thread API"
#  endif // _LIBCPP_HAS_THREAD_API
#endif // _LIBCPP_HAS_NO_THREADS

So it seems some flags are missing maybe?
