    CMake: clear cache variables when a library has changed
    
    On Windows, whenever win-setup.ps1 installs new libraries, the old
    paths become invalid. As a workaround the user can remove CMakeCache.txt
    completely or manually delete entries. Removing the whole file might
    lose custom options and clearing individual entries is tedious. Let's
    handle this automatically.
    
    Some HAVE_xxx variables from check_function_exists calls in PCAP and
    ZLIB, and one from check_symbol_exists in KERBEROS are not cleared.
    Those special cases would require too much work, the user should
    manually clear their cache in this case if needed.
    
    Fixes my local build since CARES, KERBEROS and LibXml2 were updated.
    Special care was necessary for LibXml2 as it will not set cache variable
    LIBXML2_LIBRARY when LIBXML2_LIBRARIES is already set.
