AFAIK the Xcode generator is totally untested with the Intel Fortran
plugin for Xcode, and is not currently supported by CMake.

Currently the Xcode generator does not correctly detect the compiler
that Xcode uses behind the scenes.  I've been working on this problem
for the C and C++ compilers but it is non-trivial to fix and has not
really bitten anyone yet.

As I said above, CMake has no support for Fortran with Xcode right now.
I think it happens to work in some simple cases.  You can submit a
feature request, but I don't know when we'll get to it.
