[CMake] cmake my_BouncyBall

[Richard Wackerbarth]

First let me suggest that you word your request in a more complete manner.
What "does not work"? What were you expecting and what did you get?
It is difficult, if not impossible, for us to guess.

I suspect that the problem is related to the ">" (specifying the output file in Unix).
Are you on a Un*x platform? Remember that CMake uses a different syntax because it assumes that the platform may not be Unix-based.

I also have no idea just what "BouncyBall" is supposed to do with the additional command line arguments.
They look very much like a call to the Unix "diff" command to verify that the output matches some previous version (stored in BouncyBall.out)

Provide additional details. Then we may be able to be more helpful.
