i have library integrates gtk functionnalities, , decided switch qt. created test cmake file try integrate qt5 not work because when load libary dynamically using executable "undefined symbols".

undefined symbol: _zn8uiwindow16staticmetaobjecte 

i googled lot, , not seems simple si kind of help, or comments appreciated.
