undefined iconv symbols on Mac OS X with CEGUI 0.8.7

[ma2020]

When building CEGUI using any of the project types that CMake can make, several undefined symbol errors involving iconv happen.

The fix for this problem is to add libiconv.dylib to the linking phase.

My info:
OS: Mac OS 10.8.
Compiler: GCC and Clang
CEGUI 0.8.7

This problem happens when the MacPorts version of libiconv's headers are used and Mac OS X version of libiconv.dylib is used in linking. One possible solution is to deactivate the MacPorts version of libiconv: sudo port deactivate libiconv
