    meson: Ignore warning C4251 on MSVC builds
    
    We might be building against glibmm that is built with
    __declspec(dllexport), meaning that warning C4251 will be generated as
    we are now in-turn using __declspec(dllimport).  We can just ignore this
    compiler warning, since we are pretty sure what we are doing at this
    point.
