无法导入外部库

Cannot Import External Library

本文关键字：外部 导入      更新时间：2023-10-16

我一直在跟踪那个链接中的说明。我下载了存储库。然后，我应用了这些命令:

cd C:OpenCV3.0.0opencvbuild 
cmake -DOPENCV_EXTRA_MODULES_PATH=C:opencv_contrib-mastermodules C:OpenCV3.0.0opencvsources

它创建了一个包含大量错误的CMakeError.txt文件。

我正在使用Visual Studio 2013和c++与OpenCV3.0.0编码。

请重新解压opencv，并按照以下两个链接的步骤操作:

在Windows 8上安装OpenCV 3.0

使用openCV创建Visual Studio(2013)项目
