This is likely source of the trouble: only targets after the
include_directories() line will see it. So you should move it up before the
add_executable. Also you just pass "include" here, i.e. every compiler
invocation may interpret that relative to it's current directory. You should
use absolute paths there, e.g. "${CMAKE_CURRENT_BINARY_DIR}/include".

You pass it to QT4_WRAP_CPP, so moc tries to run on it. Either don't do it or
just ignore these lines.
