cpack was causing issues with compiling remove any references to it.
change all options being set for the new libs to use the advanced_option macro
remove speex, opus is better.
added libraries:
opus
flac
libsndfile
updated:
libvorbis
libogg
openal
- Everything works as expected for now. Bare in mind libsndfile needed the check for whether or not it could find the xiph libraries removed in order for this to work.
