OpenCV使用`cv :: cvtColor`链接错误

Question

我收到此错误：

usr/bin/ld: CMakeFiles/stereo_img.dir/stereo_img.cpp.o: undefined reference to symbol '_ZN2cv8cvtColorERKNS_11_InputArrayERKNS_12_OutputArrayEii'
//usr/lib/x86_64-linux-gnu/libopencv_imgproc.so.2.4: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

在我的CmakeLists.txt中，我添加了：

add_definitions(-lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_nonfree -lopencv_objdetect -lopencv_features2d )

我正在使用这些包括：

#include "opencv2/opencv.hpp"
#include "opencv2/gpu/gpu.hpp"
#include <opencv2/opencv.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgproc/imgproc.hpp>

我可以使用opencv中的其他类型，例如cv::Mat。
