It's usually possible to selectively disable warnings for 3rd party code. A last-ditch approach is to use the following around an include:

    #pragma GCC diagnostic push
    #pragma GCC diagnostic ignored "-Wfoo"
    #include <my_3rd_party_header.h>
    #pragma GCC diagnostic pop

(Despite the "GCC" moniker, Clang supports the same approach.)
