Here's what I had to do to get it (CDC) to compile on Mac OS X 10.9 Mavericks:
-Install XCode (Get this from Apple's Website/App Store Search)
-Run XCode at least once and accept the agreement crap
-Install the XCode Command Line Tools - Open the terminal and type: xcode-select --install
-Install Homebrew http://brew.sh/
-Install SFML: http://sfml-dev.org/download/sfml/2.1/
and see the install instructions here http://sfml-dev.org/tutorials/2.1/start-osx.php
-Open the Terminal to install qt and libusb:
>brew install libusb
>brew install qt
-Open a new terminal window
-Navigate to the location where your source code is
-Should now appear in the folder as "CuteDSCapture"
-Plug in your DS/3DS Capture and play?
