问题描述
我正在尝试从源代码构建 ffmpeg 和依赖项（因为它将从 aws 上的容器中使用），但我很难使用 ffmpeg 和 pkg-config。
我编译静态库，其中包括来自源代码的 libsrt，并将生成的文件放到定义明确的目录中。 pkg-config 可以毫无问题地找到 srt，但 ffmpeg 由于某种原因没有找到（请参见下面的输出）。
这是它的样子：
构建代码（我提取了有趣的部分，也构建了其他库，我添加了打印件以便能够看到发生了什么）：

*** Building FFmpeg ***
ERROR: srt >= 1.3.0 not found using pkg-config
If you think configure made a mistake,make sure you are using the latest
version from Git. If the latest version fails,report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.
