libsndfile VS FFmpeg

There's libMuseSamplerCoreLib.dylib, which I believe was placed there by MuseScore. There's also librlottie.dylib and libsndfilelsr.dylib. I'm not sure what these are. An online search tells me the first one is related to rlottie by Samsung, "a platform independent standalone C++ library for rendering vector based animations and art in realtime," and the second one “is related to libsndfile, a C library for reading and writing files containing sampled audio data.”

If you intend to integrate also other audio formats, such as FLAC, MP3 or WAV, I recommend the use of libsndfile, which supports all of these formats with a uniform interface.

For what it's worth, I've forked FFmpeg and attempted to add CMake support (mainly for Windows since on macOS/Linux you can totally live with the configure flow unless you need to debug in Xcode). My fork is here https://github.com/rubu/FFmpeg, and the CMake stuff is inside a separate feature branch (so that I can rebase it upon incoming changes from FFmpeg master until it gets to a state where it could be actually accepted as a patch). I've been able to compile FFmpeg with VS/Clang toolchain and adding the needed codec libs via vcpkg. So if anyoned needs this and/or has any questions feel free to open issues in that fork, and I will try to make a wiki on how to compile it with different codec libararies/toolchains as soon as I have time.
