Question

我正在尝试将程序链接到OpenCV库，这些库位于：/ usr / local / lib

所以在CMakeLists.txt中我把：

TARGET_LINK_LIBRARIES(myprogram 
    opencv_core 
    opencv_imgproc
    opencv_highgui
    opencv_imgproc
    opencv_objdetect
)

继续建设，但如果我这样做：

ldd myprogram

我得到了：

...
libopencv_core.so.2.4 => not found
libopencv_imgproc.so.2.4 => not found
libopencv_highgui.so.2.4 => not found
libopencv_objdetect.so.2.4 => not found

所以为了能够运行它我必须每次将/ usr / local / lib添加到$ LD_LIBRARY_PATH

我做错了什么？

更新

我已将TARGET_LINK_LIBRARIES配置替换为此配置：

TARGET_LINK_LIBRARIES(myprogram ${OpenCV_LIBS})

现在它正确地链接了库..但是所有这些库！

Answer 1

确保正确设置了环境变量，然后在CMakeList文件中使用这些行。

FIND_PACKAGE( OpenCV REQUIRED )
TARGET_LINK_LIBRARIES( myProject ${OpenCV_LIBS} )

Answer 2

您需要配置动态库加载器以包含这些目录。添加/etc/ld.so.conf文件的路径或在.conf目录中创建/etc/ld.so.conf.d/文件
