Undefined symbols for architecture x86_64: "_CFRelease"

Question

I am quite new to the Unix world and I am trying to install a software called Meep for physics simulations. To get this I need to install a lot of libraries on my Mac OS X 10.10.5; I succeeded in many of them but I had the following error while commanding 'configure' for the script called pkg-config which works over glib.

CCLD     pkg-config
Undefined symbols for architecture x86_64:

ld: symbol(s) not found for architecture x86_64

Looking around I have understood that could be a linker problem to those symbols, but essentially I have no idea to solve the problem. Can anybody help me?

You need to add:

-framework CoreFoundation

to the link command line of your project.
