[ITK] Compile errors using ITK 4.13.1

[Ally Warner]

Hello,

I am a developer at the University of Utah and we use ITK for our software, Seg3D. Seg3D recently had a 404 error from the FFTW download because midas has been deprecated. To fix that, I am trying to upgrade our ITK version from 4.13.0 to 4.13.1. When I merged 4.13.1 and tried to build Seg3D, I received the following error: 

ATTENTION: You have enabled the use of FFTW. This library is distributed under a GPL license. By enabling this option, the ITK libraries binary that is built will be covered by a GPL license and so will any executable that is linked against these libraries.

After looking through ITK’s code changes, I noticed that in the itkExternal_FFTW.cmake file there were parentheses after the $ for the URL and the URL_HASH commands. There weren’t these parentheses in other files around these same commands. So I removed them and rebuilt. Then I received the following error:

I am not sure what to do now, and was hoping for some guidance. I’m thinking that the server might be down, but wanted to be sure that there wasn’t something else I was missing. 

Thank you for your help,
