Sicne the .rc file is in the build tree, try specifying the full path:

SET(RCFILE ${CMAKE_CURRENT_BINARY_DIR}/XX.rc)

If the rc file is generated as the OUTPUTS of a custom command then you 
do not need to mark it generated because the custom command will 
automatically do so.  Just be sure to specify it as a full path everywhere.
