Then you should probably write a test driver script that does just that and do

add_test(NAME Differ COMMAND driverScript referenceFile
$<TARGET_FILE:executable> args)

so that the "driverScript" will call "executable" with "args" and compare
its output to "referenceFile".

In your case this script may probably written as a CMake script using

execute_process
and
cmake -E compare_files

etc...
