Description

When linking against highgui, I get the following error

libcamera.a(camera.cpp.o): In function @cv::Ptr<CvCapture>::release()':
camera.cpp:(.text._ZN2cv3PtrI9CvCaptureE7releaseEv[cv::Ptr<CvCapture>::release()]+0x47): undefined reference to @cv::Ptr<CvCapture>::delete_obj()'
collect2: ld returned 1 exit status

It seems that cv::Ptr<CvCapture>::delete_obj is declared in the header as
template<> void Ptr<CvCapture>::delete_obj();
but defined in the source as
template<> inline void Ptr<CvCapture>::delete_obj() {...}

Removing the inline fixes the problem (patch attached)
