CMake boost error

[jdetter]

With CMake 2.8 on my office machine (master branch), I am getting the following error:

 CMake Error at /usr/share/cmake-2.8/Modules/ExternalProject.cmake:1401 (message):
   Could not extract tarball filename from url:

     http://downloads.sourceforge.net/project/boost/boost/1.61.0/boost_1_61_0.7z
 Call Stack (most recent call first):
   /usr/share/cmake-2.8/Modules/ExternalProject.cmake:1805 (_ep_add_download_command)
   cmake/packages.cmake:166 (ExternalProject_Add)
   cmake/shared.cmake:93 (include)
   CMakeLists.txt:17 (include)

@wrwilliams Can you reproduce this if you reconfigure?

Now I'm not getting the error anymore, this was probably just another permutation of the issue that comes up when sourceforge is down.
