我目前正在尝试在 Ubuntu 上构建 OpenCV 3。如果我只是使用默认设置运行 CMake,一切正常(配置 + 生成)并且生成的 makefile 也可以毫无问题地编译。但是,我还想构建 opencv_world 模块。因此我在 CMake ( BUILD_opencv_world
) 中启用了相应的选项。不幸的是,这样我得到了很多错误,比如 get_target_property() called with non-existent target "opencv_shape". ... CMakeLists.txt:765 (ocv_get_all_libs)
当我点击配置按钮时:

不确定这是否是您的问题的原因,但我遇到了类似的错误,而我的原因是 CMake 配置文件中的目标名称与系统中已安装依赖项的名称不同 .
我可以通过查看在 /usr/lib/x86_64-linux-gnu/cmake/<that target's name>
中声明目标的依赖项的“目标导入文件”来检查这一点。 ,并将其与依赖项目的 CMake 配置文件进行比较。
