Couldn't able to compile

[Spectre-hidN]

I have been trying to compile this but, I am getting error while trying to run the cmake .. command.

Please help me to fix this problem! 🙏 I've already installed FFMPEG and other dependencies (libav*) but, still I'am getting this FFMPEG Library missing errors.

May I ask how you solved this problem?

You need download ffmpeg source code first from ffmpeg.org,then unzip and:.

cd ffmpeg
./configure
make
sudo make install

@EchoGroot your issue is different, FFMPEG is found properly, the library not being found in your case is xxf86vm required by x11.
