Build CEGUI dependencies on OSX

Get the source code from the CEGUI homepage. Open the terminal and enter

cd <folder with source code>
mkdir build
cd build
cmake -G Xcode -Wno-dev ..
xcodebuild -configuration Debug -jobs 2
xcodebuild -configuration Release -jobs 2

The result is in <folder with source code>/build/dependencies/lib/dynamic. Copy the dependencies folder to the cegui source folder or create a symlink.
