How to import a pointer of other c++ file in QT?

I'm trying to import a struct pointer that was create class, this struct pointer is in a public slot, I try this:

FILE WITH THE STRUCT name struct.h:

typedef struct
{
   bool record;
} VIDEO;

FILE WITH THE POINTER TO BE IMPORTED test.h:

include

include "struct.h"

class Test : public QObject { Q_OBJECT

public:

explicit Test(QQmlEngine& engine, QObject* parent = nullptr);

VIDEO *_ptrVideo;

}

FILE THAT WILL IMPORT THE POINTER:

include "test.h"

*_ptrVideo->record = true;

I receive the error: Use of undeclared _ptrVideo, how can I fix this?
