RK3399Pro入门教程（7）RTSP库的使用

toybrick@debian10:~/RtspHardDecoding-master/local_rtsp/build$
toybrick@debian10:~/RtspHardDecoding-master/local_rtsp/build$ cmake ..
CMake Error: The current CMakeCache.txt directory /home/toybrick/RtspHardDecoding-master/local_rtsp/build/CMakeCache.txt is different than the directory /home/toybrick/local_rtsp/build where CMakeCache.txt was created. This may result in binaries being created in the wrong place. If you are not sure, reedit the CMakeCache.txt
CMake Error: The source "/home/toybrick/RtspHardDecoding-master/local_rtsp/CMakeLists.txt" does not match the source "/home/toybrick/local_rtsp/CMakeLists.txt" used to generate cache.  Re-run cmake with a different source directory.

请问我执行，cmake..为啥会报这个错误呢？

toybrick@debian10:~/local_rtsp/build$ sudo dnf install -y python3-devel python3-opencv python3-numpy-f2py python3-h5py python3-lmdb  python3-grpcio
sudo: dnf: command not found

为啥没有dnf呀。
我的是debian系统的原因吗？

为啥我执行cd local_rtsp/build
cmake ..
的时候会报如下的错误呢？
toybrick@debian10:~/Documents/local_rtsp/build$ cmake ..
CMake Error: The current CMakeCache.txt directory /home/toybrick/Documents/local_rtsp/build/CMakeCache.txt is different than the directory /home/toybrick/local_rtsp/build where CMakeCache.txt was created.

CMake Error: The source "/home/toybrick/Documents/local_rtsp/CMakeLists.txt" does not match the source "/home/toybrick/local_rtsp/CMakeLists.txt" used to generate cache.  Re-run cmake with a different source directory.

是路径不对，然后我修改了路径之后执行又报如下的错误了

为啥我执行这个会报这个错误呢？是我有什么依赖没有安装吗？
我查看了g++的版本
看了600多行的log，看不懂，想放弃。
楼主能踢我一脚吗？

你好，你这个怎么解决的，我也遇到这个问题

这个问题是什么原因呢？
