editor recognizes type, but compiler does not

i split a class into two classes, now the editor recognizes types, but compiler does not.

CControls.h

class CControls : public QThread
{
    CControls();
}

CThreadController.h

#include "CControls.h"

class CThreadController : public QThread
{
    Q_OBJECT
    CControls *m_controls;
}

error

/home/michaeleric/Qt_Creator_Projects/GUI/CThreadController.h:22: error: ‘CControls’ does not name a type
22 |         CControls *m_controls;
  |         ^~~~~~~~~

i dont get how the editor sees CControls as a type, but compiler does not. i dont know qhat else to look at or for.

what is going on?
