I don't think there is such option.
However if you have the list of supposedly produced files you may
check if they have been produced with
IF(EXISTS <filename>)
ENDIF(EXISTS <filename>)
With a MACRO like:
MACRO(CheckFilesExists)
FOREACH(F ${ARGN})
IF(EXISTS ${F})
MESSAGE(STATUS "${F} exists")
ELSE(EXISTS ${F})
MESSAGE(STATUS "${F} DOES NOT exists")
ENDIF(EXISTS ${F})
ENDFOREACH(F)
ENDMACRO(CheckFilesExists)
you could check
SET(FL "exist1.txt;doesnotexists.txt")
CheckFilesExists(${FL})
My MACRO is a sample but you can
MESSAGE(FATAL_ERROR ....)
when an expected file does not exists.

If you want the error to appear at build time then you'll have
to somehow add another custom command which may
cmake -P CheckFilesDoxy.cmake
the CheckFilesDoxy.cmake should be generated at CMake time
in order to contains the appropriate list of OUTPUT files used
for Doxygen custom command.
I realise it may be a bit tricky but it should work.
