Some method declarations were recently introduced without a definition:

Qt-Advanced-Docking-System/src/DockContainerWidget.h

Line 111 in ac1879d

CAutoHideDockContainer* createAutoHideContainerIfPinnable(SideBarLocation area, CDockWidget* DockWidget);

Qt-Advanced-Docking-System/src/DockWidgetTab.h

Line 185 in ac1879d

bool mousePressed() const;
