The extension's not going anywhere, and it can't do anything fluidsynth can't.
The code maintenance and bloat is not worth keeping around, and ideally the AL
API would be able to facilitate MIDI-like behavior anyway (envelopes, start-at-
time, etc).
This example shows proper timing and A/V synchronization with an OpenAL stream.
Requires the in-progress AL_SOFTX_source_length extension to avoid manually
keeping track of the buffer queue length.
This should make it easier to build the examples on 64-bit, where there are no
premade dev libs for SDL1 on 64-bit mingw. FindSDL_sound.cmake has been
updated to accept SDL or SDL2.
Some (all?) versions of cmake seem to get a bit confused when an old-style
FIND_PACKAGE_HANDLE_STANDARD_ARGS call fails, and the scripts attempt a new-
style call later on. It continues to think it's using old-style, acting as if
REQUIRED_VARS is the message and looks for a VERSION_VAR variable.
