prepare_dependencies.py errors

[Andrew Patterson]

I'm trying to build the library for Windows -- I know, something of an uphill battle -- but I've managed to get a reasonable way along, though I've had to work around some glaring problems:

1. prepare_dependencies refers to several URLs that no longer exist:
• http://google-glog.googlecode.com/files/glog-0.3.3.tar.gz
  
• http://googlemock.googlecode.com/files/gmock-1.6.0.zip
  
• http://gflags.googlecode.com/files/gflags-2.0-no-svn-files.tar.gz
  
2. While converting cmake -> nmake it complains of missing CMakeLists.txt

I solved the missing dependencies by locating them in their new homes on github and installing them manually in such a way that the script thinks it performed the operation previously. This lead to some compilation errors in gflags that were fortunately easily solved (missing spaces between PRId32 prefixes & "%"). It *seems* to make cmake -> nmake happier if I add empty CMakeLists.txt where it complains they're missing. 

My questions are fairly straight forward: 

1. Is anyone maintaining the cpp-client-master repo? It seems like those dead links should be fixed, and there do seem to be viable solutions (googlecode.com has been gone for a little while now!)
2. Am I doing the right thing w.r.t. to empty CMakeLists.txt files?

I'm currently stuck on configuring openssl and (I think) libssh2. I expect it's a long way to go still, but I thought I'd ask the above questions while it's still fresh in my mind.

Thanks!
