Debian packages for Chipmunk

[Miriam Ruiz <miriam@debian.org>]

Hi Scott,

My name is Miriam, I'm member of the Debian Games Team, and I'm
currently packaging Chipmunk for Debian. For doing so, I had to patch
a couple of files from the cmake building system, in order to add -lm
to the compilation, and to provide a proper SONAME, instead of just
having a different version number for the libraries regardless of
possible ABI changes.

I'm attaching my patches to this mail, in case you might be
interested, and I also wanted to ask you if you plan to have a SONAME
assigned by you instead of a different one for every possible Linux
distribution. If you need/want any help, please, just ask :)

Greetings, and thanks for your work,
Miry
