hey bslaughter, welcome to the list.
I have never created xcode projects manually so I cannot really
comment on your approach. Is there a specific reason that you are
doing it this way? The canonical way is to use cmake to generate the
xcode projects (or any other supported IDE). It is described on the
setup page how to do this. With the next release we will probably
distribute with xcode, vs2008, code::block, Makefile projects. Until
then cmake is the way to get things working.
Best,
/stefan
