librtmp not found using pkg-config

librtmp not found using pkg-config

我遇到这种情况是：MAC下，ffmpeg config的时候

这时候找到了解决办法 https://github.com/crystal-lang/crystal/issues/4745

终端：export PKG_CONFIG_PATH=/usr/local/opt/openssl/lib/pkgconfig

comment：

as a side note, it works well after adding openssl to pkg-config's path

since it's (openssl) not default anymore on macOS High Sierra (switched to LibreSSL instead)

I added this to my .zshrc (.bashrc if you're using bash) after installing openssl with brew install openssl and it worked great! Thanks
