为什么我不能构建Qt 6.5.0？我需要6.5.0，因为6.5.1把我的项目搞砸了，他们从维护工具中删除了6.5.0。我把所有东西都安装好了。但是运行configure.bat时说某个文件丢失了。我有：

• CMake 3.26.4
• 来自winlibs的GCC 12
• 简体中文

错误是：

-- Configuring submodule 'qthttpserver'
-- Configuring submodule 'qttools'
CMake Error at C:/MinGW/lib/cmake/llvm/LLVMExports.cmake:677 (message):
The imported target "LLVMDemangle" references the file 

   "C:/MinGW/lib/libLLVMDemangle.dll.a"

but this file does not exist. Possible reasons include:

* The file was deleted, renamed, or moved to another location.
* An install or uninstall procedure did not complete successfully.
* The installation package was faulty and contained
  "C:/MinGW/lib/cmake/llvm/LLVMExports.cmake"
but not all the files it references.

我尝试从here安装MinGW-w 64的LLVM工具链。但它没有工作，我也尝试安装LLVM使用官方安装程序，它仍然安装，它仍然不工作。
