When build on Ubuntu, paddle's requirements(cmake, protobuf, blas, etc.) can be installed using following way:

sudo apt-get install -y g++ make cmake build-essential libatlas-base-dev python python-pip libpython-dev m4 libprotobuf-dev protobuf-compiler python-protobuf python-numpy git

But if i want to build paddle on other platform which can not connect to internet, the only way is to build these requirements(cmake, g++, blas, protobuf, python) from downloaded source code.

So i want to confirm is this ok to install these requirements from source.

thanks~
