c++ - 无法导入外部库

Question

我一直在跟踪 link 中的说明.我下载了存储库。然后，我应用了这些命令:

cd C:\OpenCV3.0.0\opencv\build 
cmake -DOPENCV_EXTRA_MODULES_PATH=C:\opencv_contrib-master\modules C:\OpenCV3.0.0\opencv\sources

它会创建一个包含大量错误的 CMakeError.txt 文件。

我正在使用 Visual Studio 2013 并使用 C++ 和 OpenCV3.0.0 进行编码。

Answer 1

请重新解压opencv，按照以下两个链接的步骤操作:

Install OpenCV 3.0 on Windows 8

Create an Visual Studio (2013) Project with openCV

让我知道这是否适合你..
