c++ - 未找到 OpenCV 库 - 带有柯南的 cmake

问题描述

我有一个描述我想要包含的内容的 conanfile（在这种情况下，主要是 OpenCV 部分），以及一个相应的 cmakelists。运行 conan install 然后 cmake 时，它可以工作，但在编译期间，无法包含 OpenCV 库。相同的代码适用于 Windows，所以我想知道我是否忘记了一些设置。

似乎找到了包含文件，但是在链接时：

`undefined reference to `cv::imshow(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, cv::_InputArray const&)''

柯南文件.py：
