Fix #208006: Add built-in MP3 support for Windows #3395
expects lame_enc.dll (from https://lame.buanzo.org/#lamewindl) to be found at the same place as libogg.dll, libsndfile-1.dll, libvorbis.dll, libvorbisfile.dll and portaudio.dll
AppVeyor build expected to fail, lame_enc.dll needs to get added to http://utils.musescore.org.s3.amazonaws.com/musescore_dependencies_win32.7z first
Not sure, we may want to use the same approach for master too, at least until there's MP3 support in libsndfile?
I will try it first. Since we have the luxury of downloading binaries for PR now : https://ci.appveyor.com/project/MuseScore/musescore/build/1.0.129/artifacts
If it works, it's probably worth doing something cleaner on master, and remove the whole lame loading scheme. That would mean having lame deployed on all platforms. On linux, it's probably just adding a dependency but on mac... we need to have a version compiled on an old mac system to be compatible...
