Uses add_custom_command() to add rules for generating these directories, rather than creating them only when CMakeLists.txt runs. With this change, you can manually delete Packaged from the build directory without causing subsequent builds to fail.
About Aerofoil
Aerofoil is a port of John Calhoun's Glider PRO, the classic paper airplane game for Apple Macintosh computers released in 1994.
The port features a 90's-style GUI, gamepad support, high-quality upscaling and color correction, a full port of the level editor, a set of import tools for unpacking and converting the vast majority of existing community content, and a new touchscreen interface for mobile devices.
