CMake Error at /usr/lib/llvm-12.0/lib64/cmake/llvm/LLVMExports.cmake:1153 (message):
  The imported target "LLVMDemangle" references the file

     "/usr/lib/llvm-12.0/lib64/libLLVMDemangle.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

     "/usr/lib/llvm-12.0/lib64/cmake/llvm/LLVMExports.cmake"

  but not all the files it references.

Директива: -DBUILD_SHARED_LIBS:BOOL=ON не влияет на сборку (всё также падает).
