[Insight-developers] TestDriver Test

[Bill Lorensen]

Right now, cmake generates several configurations. I think that most users only use one and the others often get in the way since sometimes the wrong configuration gets picked.

It would be nice if the user could have cmake just generate one of these. Would this have any performance improvemement?
