Are you using CMake 2.8.6?

Is the following line in your top level CMakeLists.txt file?

  set(CMAKE_XCODE_EFFECTIVE_PLATFORMS "-iphoneos;-iphonesimulator")

If not, try both of those and let me know if it's still wrong. The
effective platform stuff is new in 2.8.6, and there are probably still
some rough edges for "complex" projects...


HTH,
