[CMake] COMMAND Doesn't Always Return Correct Exit Code

[David Cole]

Probably only necessary for NMake Makefiles, but possibly also for
Visual Studio. Is the implementation of ant that gets called here a
".bat" or ".cmd" file?

Using "call" like that should work as long as it goes through the
Windows cmd prompt. You may have to conditionalize the use of "call"
depending on how cross-platform your project needs to be.


Cheers,
David
