    Description

      We get teached to use QT_DECLARE_QESDP_SPECIALIZATION_DTOR internally.

      Some people disagree or even report problems on windows as it leads to linker problems with ltcg enabled and thus recommend the _EXPORT version of it.

      We need to know what the correct usage is. Where the problems are on windows and how to apply it correctly in the future.
