I am compiling Paddle on Ubuntu 14.04.

I followed the instruction on http://www.paddlepaddle.org/doc/build/build_from_source.html, but got compilation error if I use 'sudo apt-get install libgflags-dev' to install gflags.

""" -- Failed to find installed gflags CMake configuration, searching for gflags build directories exported with CMake. -- Failed to find an installed/exported CMake configuration for gflags, will perform search for installed gflags components. -- Found Gflags: /usr/include
-- Found PY_wheel: /usr/local/lib/python2.7/dist-packages/wheel
"""

It seems I need to build and install gflags from source.
