Description
i'm using statically linked qt and get the following duplicate symbol:
[2023-05-03T03:47:05.488Z] duplicate symbol 'NI_6_5_0::QIIOFHelper::initRead()' in: [2023-05-03T03:47:05.488Z] /Volumes/build/NIBuild/3rdparty/Qt/Qt-6.5.0-macx-clang-static/./plugins/imageformats/libqmacheif.a(qiiofhelpers.cpp.o) [2023-05-03T03:47:05.488Z] /Volumes/build/NIBuild/3rdparty/Qt/Qt-6.5.0-macx-clang-static/./plugins/imageformats/libqmacjp2.a(qiiofhelpers.cpp.o)
qiiofhelpers.cpp is directly compiled into both plugins, which works for dynamic linking, but is problematic when using static linking, as downstream code may use `-all_load` or the like to force all static library members to be loaded (unity builds may similar troubles)
