链接期间无法找到 OpenCV（从源代码编译）

我正在尝试编译qgifer-0.2.1-source来自 Ubuntu 中的源代码。我已安装所有依赖项。我按照源代码 README 中的以下说明进行编译。

cd qgifer_source_dir
mkdir build && cd build
cmake .. -DCMAKE_INSTALL_PREFIX="/usr/local/" -DQUIET_MODE=ON
make
sudo make install

一切都进行得很顺利，包括编译和 obj 创建，但是当它开始链接时，文件frameplayer.cpp失败了。

这似乎是 OpenCV 包的问题。我已按照以下说明安装了 OpenCV操作说明。

OpenCV详细信息：

$ pkg-config opencv --libs
-L/usr/local/lib -lopencv_shape -lopencv_stitching -lopencv_objdetect -lopencv_superres -lopencv_videostab -lopencv_calib3d -lopencv_features2d -lopencv_highgui -lopencv_videoio -lopencv_imgcodecs -lopencv_video -lopencv_photo -lopencv_ml -lopencv_imgproc -lopencv_flann -lopencv_core -lopencv_hal

错误文件frameplayer.cpp的头部包含：

#ifndef FRAMEPLAYER_H
#define FRAMEPLAYER_H

#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgproc/imgproc.hpp>

OpenCV 在我的系统中安装如下：

  1. 这包含 OpenCV 的 cmake 配置文件

    /usr/local/share/OpenCV

  2. hpp 文件 (core, highgui ..) 位于

    /usr/local/include/opencv2

这些我试过，但没有用

  • 重新安装 OpenCV

  • hpp通过使用完整文件路径更改头文件来再次配置源，并make

任何帮助，将不胜感激。
