Wengophone, FFMPEG, CMake, and Headache
I decided that I wanted to torture myself again by trying to get a stable version of Wengophone built on my system. I'm using the PKGBUILD for 2.1.1 from AUR. Here's the problem: Wengophone finds all of the correct libraries, compiles fine, but it can't link against FFMPEG's libavcodec. Number 3 from this thread is correct; avcodec.h does not have the 'extern C' code.

Patching FFMPEG is not a good option for me. And if Wengophone actually compiled against the internal one they shipped (it doesn't), I would rather use the one I have. So here's my question:
How do I get CMake to link up this file? I've tried the few things that I can find to no avail. Any ideas will be appreciated.

Re: Wengophone, FFMPEG, CMake, and Headache
i tried Wengophone many times but it never work on my system, it runs on my system but it does not do anything like voice-chatting . i installed Ekiga and it runs great without any problems. as a bonus, i can choose different codecs when my bandwidth goes down, a situation where all other clients,e.g. Skype, fail without any trace

Re: Wengophone, FFMPEG, CMake, and Headache
I finally broke down and edited avcodec.h to see if I could get a useful build, and not surprisingly, I couldn't. Wengophone is know to have problems with newer versions of GCC, as well as some versions of QT4.
Skype was working alright here for VOIP until I upgraded. I haven't spent any time trying to figure out what's wrong yet. Ekiga seems to work good, but none of my friends use compatible phones.
I think the moral of the story is that I need new friends if I'm going to get to use a video phone in the near future!
----EDIT---
I still would like to know how to get CMake to import that library. FFMPEG is C; Wengophone is C++. Why CMake can find the file in the first place but not link to it is something I don't understand. It would make sense to me if it where, say, C and Python, but not here.
