prj-opencv-cpp中C++调用的问题

[Iker]

根据prj-opencv-cpp中编译后，运行build/demo测试成功，但是编译demo.cpp报错
In file included from demo.cpp:3:0: cpp/cv_dnn_centerface.h:17:1: warning: ‘typedef’ was ignored in this declaration [enabled by default] }; ^ /tmp/ccvuKSBX.o: In function main':

demo.cpp:(.text+0x5aa): undefined reference to Centerface::~Centerface()' collect2: error: ld returned 1 exit status

opencv 3.4.15可运行
