I am pleased that in my case it all worked so easily using CMake.

The script on the web page I gave does it all for you and if for no 
other reason, I found it to be a terrific way to compile the whole GTK2 
libraries.

I will get back to doing the GTK+OSX and check that it also works if you 
prefer to use that.

On machines where the jpeg, png, OpenEXR libraries are installed and the 
include files can be found, they do not get built and the system ones 
are used instead. My kubuntu installation had all the jpeg and thus I 
did not see what to do when it was not available. On OS-X, there was no 
jpeg library so I had to modify CMake to create it from source. The 
current status is that zlib, jpeg, lcms and OpenEXR will build from the 
directories in the cinepaint distribution. Somehow, png seems to work 
without having to compile libpng. But I am a bit confused as to how that 
is.

It is for such reasons that testers are really needed as I cannot create 
"sandbox" configurations of all the combinations of libraries that may 
or may not exist on a system. Testers who can report on which system it 
works or break would greatly help me. I can quickly fix build problems 
if told what breaks.
