I've removed fink from my mac long time ago. It may be convenient at first, 
because it provides many packages and automatic dependencies, but after some 
time you will realize that you don't have a nice GUI front-end of cmake, or 
some packages are compiled without a feature that you want, or the versions of 
some other packages are ancient and never get updated ...

For cmake, there are nice native builds here:

glib and gthread are mandatory for fluidsynth >= 1.1.0, but the other 
libraries can be avoided if you don't need the functionality. For instance, we 
use dbus in Linux to communicate with rtkit, but we don't use it in Mac for 
anything. Readline and libsndfile are very useful and interesting in all 
platforms, but maybe your users can live without them ...

The libraries in /usr/local are typically installed by the user from sources. 
/usr/lib/libstdc is provided by Apple, and /sw is the fink prefix.

You need to download the sources, build and install them yourself. Or you may 
look for alternatives to fink. Good luck.
