我正在尝试为 ARM 目标交叉编译 OpenCV 4.5.1。我的主机系统是 Linux 20.04（基于 Intel）。我正在使用 CMake 3.16.3。没有额外模块的编译工作正常。当我添加它们时，我在最后得到一个链接错误：

[ 86%] Building CXX object modules/gapi/CMakeFiles/opencv_gapi.dir/src/api/kernels_video.cpp.o
[ 86%] Linking CXX executable ../../../../bin/opencv_waldboost_detector

collect2: error: ld returned 1 exit status

我知道问题是因为找不到两个库libdl和librt。缺少的库位于非标准路径上。我试图将 LD_LIBRARY_PATH 设置为包含请求的库的文件夹，但没有运气。

不知道我还能尝试什么。错误消息说尝试使用 -rpath 或 -rpath-link，但我不知道该怎么做。
