      Description

      Trying to build an iOS application with CMake + Xcode generator that uses plugins will fail at link time with:

      ld: '/Volumes/T3/Dev/qt/qt5_cmake/builds/dev-ios-super/qtdeclarative/src/quick/CMakeFiles/qtquick2plugin_init.dir/qtquick2plugin_init.cpp.o' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. file '/Volumes/T3/Dev/qt/qt5_cmake/builds/dev-ios-super/qtdeclarative/src/quick/CMakeFiles/qtquick2plugin_init.dir/qtquick2plugin_init.cpp.o' for architecture arm64

      The plugin initializer object libraries don't get the bitcode flags that we set when building other Qt libraries.
      Happens for both qt plugins and qml plugins initializers.

      Can be worked around by disabling the ENABLE_BITCODE setting in the Xcode project build settings.
