尝试运行OpenCV代码时出现“没有规则可定位”错误

Question

我正在尝试从https://docs.opencv.org/master/db/df5/tutorial_linux_gcc_cmake.html运行示例代码。我使用Ubuntu16。我在/home/marcin/opencv/目录中安装了OpenCV。我像示例一样使用CMakeLists.txt文件，并添加了行

set (CMAKE_CXX_STANDARD 11)

我在码头跑

cmake -D CMAKE_PREFIX_PATH=/home/marcin/opencv/build

，我得到正输出。但是当我尝试运行make命令时，我得到了：

make[2]: *** No rule to make target '/home/marcin/opencv/build/lib/libopencv_core.so.4.0.1',
needed by 'DisplayImage'.  Stop.  
CMakeFiles/Makefile2:67: recipe for target 'CMakeFiles/DisplayImage.dir/all' failed  
make[1]: *** [CMakeFiles/DisplayImage.dir/all] Error 2
Makefile:83: recipe for target 'all' failed

Answer 1

按照@Tsyvarev建议，我又重新安装了一次库。好像坏了。
