[CMake] Batch Files in CTest (instead executables)

[David Graf]

Hello David

The problem I have is not located in the batch file. The EXIT is executed. But if the /B option is on, ctest doesn't detect failures anymore. The batch script must be killed by executing EXIT without the '/B' options. But then, the batch script cannot be used anymore from the command line because it kills the command line all the time.

I didn't find a clean solution in the meantime. Now, I am using different scripts. One to execute executables form ctest (without /B option). And one to execute executables from the command line (with /B option).
