Then it should definitely be possible.

Before calling "message(FATAL_ERROR" write out a file with "file(WRITE" to
indicate the return value that you want.

Then after the script is done (or after ctest_configure if you're producing
the FATAL_ERROR in a CMakeLists), use "file(READ" in the ctest script to
read the file that has the return value in it.

This may or may not be "too much effort" for what you're trying to do, but
it should certainly be possible...


HTH,
