Use Q_DECL_EXPORT/IMPORT instead some internal kde4 cmake checks
Review Request #126147 - Created Nov. 23, 2015 and submitted
Handling the visibility support by our own is not reasonable nowadays - just use the Qt macros should be fine.
The part can still be loaded fine, linking also works - so all is exported as expected.
|the part is in a plugin, nothing can link to it, it shouldn't be exported.||David Faure|
