Bug#991989: libclang-13-dev: dead symlink to shared library

[Christian Göttsche]

Control: reopen 991989
Control: retitle libclang-13-dev: cmake find_package implementation broken

The previously dead symlink issue has been resolved, but the cmake
script does still not work;
it references the non-existing file
'/usr/lib/llvm-13/lib/libclang-13.so.13.0.0':


-- IWYU: out-of-tree configuration
CMake Error at /usr/lib/llvm-13/lib/cmake/clang/ClangTargets.cmake:706
(message):
 The imported target "libclang" references the file

    "/usr/lib/llvm-13/lib/libclang-13.so.13.0.0"

 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-13/lib/cmake/clang/ClangTargets.cmake"

 but not all the files it references.
