[CMake] Batch Files in CTest (instead executables)

[David Cole]

Try something like this instead:
SETLOCAL
SET PATH=...;%PATH%
execute_something.exe
set my_error=%ERRORLEVEL%
IF %my_error% neq 0 (
 EXIT /B %my_error%
)
ENDLOCAL

I think the problem is probably that ERRORLEVEL is changing to 0 after you
execute the batch script IF command... Saving it in your own variable
prevents that sort of "sole last error" madness...

Let me know if that does not work. This should be working as you expect.
