CMake Error at /usr/share/cmake-2.8/Modules/ExternalProject.cmake:694 (message):
Could not extract tarball filename from url:
I looked in the top level CMakeLists.txt file and found the line:
option(USE_SYSTEM_ZLIB “Should we use the system zlib?” OFF)
So I changed that to ON, cleared out the build directory, and re-ran
cmake, and this time got the error message:
– Looking for _POSIX_TIMERS - found
– Found ZLIB: /usr/lib/libz.so

It looks like a problem with the zlib URL, what version of CMake are
you using there? I will take a look at this.

I suspect you will be using an older version of CMake actually, one
that didn’t support checking the MD5 of downloaded files. If possible,
you could upgrade CMake, or failing that take out the MD5 arguments in
your local copy.
