There are many configuration options available. I will assume that you are just trying to build ITK with the default options, if you are trying to build WrapITK let us know as the advice will change a little.

In the default configuration testing and examples are enabled. This adds a dependency to download data. So this should be disabled if network access needs to be avoided. While I don't think it has been done yet, it should be possible to create a second tar ball of the data, and that will either need to be extracted into a specific location in the source code, or an environment variable will need to be specified to it's path.

Turning on FFTW ( off by default ), will automatically download the source code and compile if that option is turned on, and a system library is not specified.

By changing the configuration options and specify dependencies to the system libraries and headers, there should not be a need for downloading during compilation. ( Perhaps we should just have an AIRPLANE_MODE configuration option ).


By default no library or library source code should need to be downloaded. So I am a little confused by your observation. Do you have the specific library it is downloading and the message it produced?
