[Insight-developers] portable temporary file name generator function?

[kent williams]

I have need to generate some temporary filenames, in order to write out
images for external programs to use as inputs.

I notice there's no temporary file name generator in itksys::SystemTools.

Shouldn't there be?

I'd can write one, no doubt, but don't have Windows builds to test it on.

Is there one buried somewhere in CMake?
