glog doesn't build against gflags 2.1

GoogleCodeExporter commented 8 years ago

What steps will reproduce the problem?
1. Install gflags 2.1
2. Compile glog from fresh checkout

What is the expected output? What do you see instead?

Errors:

Additional info:
gflags 2.1 was released recently -- March 20.
I'm able to compile just fine using gflags 2.0

Hadn't seen this issue when I searched and opened my own (195). 
In the recent gflags release, the (default) namespace is change from 'google' 
to 'gflags' and the GFLAGS_NAMESPACE variable is added for compatibility. It is 
not desirable to build the gflags library with a non-default value for 
GFLAGS_NAMESPACE because other projects may rely on it.

Here's a patch!

The namespace is hardcoded right now. If I should change that, let me know.
