      Description

      Since a7fc1631a707e067d3b90d79d6f514096891b20dit fails to link said plugin:

      ld.exe: client.o:client.cpp:(.text+0x12af2): undefined reference to `__imp__ZN22LanguageServerProtocol29WorkDoneProgressCreateRequest10metho
      dNameE'

      I had the same issue with my own code, constexpr static variables are not exported in the DLL, I had done something like:

      #ifdef Q_OS_WIN
      #    ifdef BUILD_LVS_LIBRARY
      #        define EXPORT_LVS_LIB __declspec(dllexport)
      #    else
      #        define EXPORT_LVS_LIB __declspec(dllimport)
      #    endif
      #     define EXPORT_LVS_LIB_CONSTEXPR __declspec(dllexport)
      #else
      #    ifdef BUILD_LVS_LIBRARY
      #        define EXPORT_LVS_LIB           __attribute((visibility("default"))
      #        define EXPORT_LVS_LIB_CONSTEXPR __attribute((visibility("default"))
      #    else
      #        define EXPORT_LVS_LIB
      #        define EXPORT_LVS_LIB_CONSTEXPR
      #    endif
      #endif
      

      No idea how you want to handle stuff like that, otherwise I had created a change.
