opencv - 使用 cmake for raspberry pi 交叉编译 opencv 代码失败

Question

我正在尝试从 ubuntu18.04 x86 机器为覆盆子编译示例代码。我的 cmake 和 toolchain.cmake 文件丢失了一些东西，我无法制作，尽管 cmake 工作得很好。请帮忙。

我已经在我的电脑上测试了用于构建的 cmake 和输出 makefile。我工作正常，但在交叉编译期间失败。我试图编译的代码可以在这里找到：https ://github.com/adamb/opencv-samples/blob/master/hello-world.cpp

我对所有这些交叉编译都很陌生。系统 rpi 和 x64 pc 都使用以下命令安装了 opencv：

sudo apt-get install libopencv-dev
