Original issue reported on code.google.com by chris.we...@gmail.com on 12 Feb 2014 at 5:23

Right, that's another small thing we need to modify. Here's a patch that never 
made it into FFmpeg:
http://ffmpeg.org/pipermail/ffmpeg-devel/2012-May/124142.html
And we need to do the same thing for pp_help, too.

I should document that somewhere, but I'm probably going to include that in 
future build scripts for the JavaCPP Presets anyway:
http://code.google.com/p/javacpp/wiki/Presets

At the very least, I'll keep this issue up as a reminder, thanks!

I've added everything in the cppbuild.sh scripts of the presets. Check it out:
http://code.google.com/p/javacpp/wiki/Presets
and let me know if you encounter anything missing, thanks!

All the nitty-gritty about how to build the native libraries has been included 
as scripts in the latest release of JavaCPP and JavaCV 0.8. A lot of other 
things have changed with this new version, so please make sure to read the news 
release here:
    http://bytedeco.org/release/2014/04/28/first-release.html

Incidentally, the project is now hosted on GitHub:
    https://github.com/bytedeco/javacv

Enjoy!
