Build fails on master.

When building TizenFX using the build instructions the build fails with the below error (it happens muliple times, but with the same error):

/p/misc/tizen/nui/dali-core/dali/public-api/signals/callback.h:235:31: error: cast between incompatible function types from ‘Dali::CallbackBase::Dispatcher’ {aka ‘void (*)(Dali::CallbackBase&)’} to ‘Dispatcher’ {aka ‘bool (*)(Dali::CallbackBase&, Dali::Actor, const Dali::WheelEvent&)’} [-Werror=cast-function-type]

Sorry. I should have filed it under dali-core. Moving it there now.
