[ITK] [ITK-dev] Installed External Module list

[Lowekamp, Bradley (NIH/NLM/LHC) [C]]

Matt,

Yes, that is the documented usage. I do that for the subdirectories where I am about to use the components [3,4]

But at the top-level, I am trying to ask what components are installed [1,2] so I know what options to turn on and how to control some aspects for the build process. How do I get a list of modules available?

I am now testing with find_package’s “OPTIONAL_COMPONENTS” to see what happens.

Thanks,
Brad
