well I got it to work going through every different variation I could and this is what worked in the end...

#define PRAGMA_PATH "%EXE_DIR%\\work\\terrain"

*note* there is no semicolon and the use of double back slashes...so "in case"anyone has the same problem try the previous define.
thanks all.
