cmake找到opencv库的路径，但make找不到opencv函数Rodrigues

Question

我正在从github构建一个项目。本项目使用OpenCV。cmake用于构建项目。cmake的输出如下：

OpenCV information:
  OpenCV_INCLUDE_DIRS: /usr/local/anaconda3/envs/test-caffe/include/opencv;/usr/local/anaconda3/envs/test-caffe/include
  OpenCV_LIBRARIES: opencv_xphoto;opencv_xobjdetect;opencv_ximgproc;opencv_xfeatures2d;opencv_tracking;opencv_text;opencv_surface_matching;opencv_structured_light;opencv_stereo;opencv_saliency;opencv_rgbd;opencv_reg;opencv_plot;opencv_optflow;opencv_line_descriptor;opencv_hdf;opencv_fuzzy;opencv_face;opencv_dpm;opencv_dnn;opencv_datasets;opencv_ccalib;opencv_bioinspired;opencv_bgsegm;opencv_aruco;opencv_videostab;opencv_videoio;opencv_video;opencv_superres;opencv_stitching;opencv_shape;opencv_photo;opencv_objdetect;opencv_ml;opencv_imgproc;opencv_imgcodecs;opencv_highgui;opencv_flann;opencv_features2d;opencv_core;opencv_calib3d

如您所见，cmake已经找到了opencv目录。但下面是make命令抛出的错误：

/home/iimtech5/3DMM/3dmm_cnn-master/modules/PoseExpr/src/BaselFaceEstimator.cpp:207:2: error: ‘Rodrigues’ is not a member of ‘cv’
cv::Rodrigues(rMatP, rVec);
  ^
make[2]: *** [modules/PoseExpr/CMakeFiles/PoseExprLib.dir/src/BaselFaceEstimator.cpp.o] Error 1
make[1]: *** [modules/PoseExpr/CMakeFiles/PoseExprLib.dir/all] Error 2
make: *** [all] Error 2

有没有人能告诉我为什么会出现这个错误？我已经尝试了所有的方法来了解这个错误的含义，但是失败了。

提前谢谢。

确保您已经在linux: OpenCV_INCLUDE_DIRS: /usr/local/anaconda3/envs/test-caffe/include/opencv;/usr/local/anaconda3/envs/test-caffe/include上安装了openCV

上面的路径是python中的opencv

使用sudo apt-get Install libopencv-dev安装opencv
