Unable to install cddlib #85

Hello,

I'm currently trying to install iris, but it seems that those two lines are complaining when I try to install.

In fact, I got this error message:

This sounds like very similar issue to this issue but I could not install iris even though I modified URL based on this page.

So, it'd be very appreciated if you would let me know the correct URL and hash in CMakeLists.txt. Thank you so much!
