Yes, we should bump the version. The PIC feature is not 'fully automatic'. 
We'll need this once in every project which wants to do a try_compile:

if (Qt5_POSITION_INDEPENDENT_CODE)
  set(CMAKE_POSITION_INDEPENDENT_CODE ON)
endif()

All targets built using Qt5 should use the qt5_use_modules function, which 
also works without the above snippet.

A docs change for this will integrate soon:

Thanks,

Steve.
