applewm.c:42:34: error: HIServices/Processes.h: No such file or directory

Not sure if this is relevant but when compiling
libAppleWM on a linux machine I receive this error:

applewm.c:42:34: error: HIServices/Processes.h: No such file or directory
applewm.c: In function 'XAppleWMSendPSN':

applewm.c:364: error: 'noErr' undeclared (first use in this function)
make[2]: *** [libAppleWM_la-applewm.lo] Error 1

Should I even bother with this lib, or should
I add some header to compile this lib in?
