Thank you for this link, that was I was asking for!

How is this supposed to work? From openh264 pov?

They offer libraries for download but no header? 
How do I know where to put the header files so 
that random applications (including but not 
limited to FFmpeg) finds them?

The answer apparently is "use pkg-config" (which 
is imo an abomination) which doesn't exist on 
osx by default and which afaict is also not 
part of the binary distribution.

Sorry to say it but thank you for proving my 
suspicion that this whole thing is not really 
thought through...

I suggest you force libopenh264 enabled in 
config.h and config.mak and put the headers 
into /usr/include/wels or /something/wels 
and use --extra-cflags=-I/something

I will try to provide a fix for this incredible 
mess.
