All,
Oh, umm, wait. How do I specify the 10.4 Universal SDK? Maybe that
is it where I specify it on XCode, but I see nothing in my CMake
file that would select a particular SDK so would it be using 10.5
automatically? How does CMake decide this?
Which would make Michael right that maybe this was introduced in 105.
Sorry for top posting, I thought it might be easier for the way the
thread is going.
Thoughts?

Yep, that would probably be it. What you have to do is setting
CMAKE_OSX_SYSROOT=/Developer/SDKs/MacOSX10.4u.sdk and CMAKE_C_FLAGS='$
{CMAKE_C_FLAGS} -mmacosx-version-min=10.4'. Probably you have to add
the same to all CMAKE_*_LINKER_FLAGS.
Below CMake code compiles MoreFilesX just fine (most of it is devoted
to working around issue #6195 and checking that we use a suitable SDK
and deployment target).
