[cairo] [cairo osx] OS X example

[Ipacs Péter]

Oh boy .. this is getting deeper and deeper.

Macport's Cairomm port does not contain quartz_surface.h since it is not
included in the official 1.2.4 version (
http://cairographics.org/releases/cairomm-1.2.4.tar.gz). I've checked out
cairomm from CVS and I've managed to install it with quartz support (freshly
checked out version is 1.0). Apart from the versioning mistery so far so
good.
Now the stupid-beginner question: how can I use the installed cairomm from
Xcode? It is installed under /usr/... that is unfortunatelly unusable from
Xcode + I have no experience using 3rd party libraries within Xcode.

Could you adwise something?:)

Cheers,
P
