This fails on "cannot set property on ALIAS target", CC @traceon
As we don't use X-Code, I temporarily removed it.

OK, I'll submit adjustments/fixes, after this change is merged.

There is inefficient path for allocating and deallocating memory chunks of size 1048591 bytes. |

Something is still wrong with allocations from zlib-ng. |

This can be changed just to this to fix the issue:
# Skip aliases and INTERFACE library targets, since FOLDER property is not available for them.
get_target_property (_target_aliased "${_target}" ALIASED_TARGET)
get_target_property (_target_type "${_target}" TYPE)
if (_target_aliased OR _target_type STREQUAL "INTERFACE_LIBRARY")
return ()
endif ()

@alexey-milovidov is it just to test this allocator, or it is considered as a real replacement? If yes, what are the benefits? |

Let's try again. The chances it will be merged are low. |

Yes, it gives some improvement, around 3% on average. |

Half of performance comparison runs were killed by OOM killer - most likely due to increased memory consumption. |

Bug related to zlib-ng is still not fixed. |

We need help to make it production ready. |

I can't understand - if hualloc still consumes 4x more memory as in #31376 (comment) in exchange for 10% speedup - do you expect that customers will approve that exchange?! |

It maybe due to some easy case that will be easy to fix. We just need to figure out - why it has 4x more memory consumption. |

Note: the issue with zlib-ng should be definitely trivial to fix. |

For some queries it gives around 1.5x speedup. |

Let's finally close this PR, because it is difficult to merge. |
