AbdealiJK 8da4053c30 setup.py: Don't fail if pip fails in cmake err msg 
When cmake is not found, the error message suggests what to do to
install cmake. But if `distro` is not found and cannot be installed,
the distro specific error message cannot be shown. Hence, we simply
ignore this and continue on.

Also, make the pip install quiet so that if there is an error message
in that, the user does not get confused by it.

"""setup for the dlib project
Copyright (C) 2015 Ehsan Azar (dashesy@linux.com)
License: Boost Software License See LICENSE.txt for the full license.
This file basically just uses CMake to compile the dlib python bindings project
located in the tools/python folder and then puts the outputs into standard
python packages.
To build the dlib:
python setup.py build
To build and install:
python setup.py install
To package the wheel:
python setup.py bdist_wheel
To repackage the previously built package as wheel (bypassing build):
python setup.py bdist_wheel --repackage
To install a develop version (egg with symbolic link):
python setup.py develop
To exclude/include certain options in the cmake config use --yes and --no:
for example:
--yes DLIB_NO_GUI_SUPPORT: will set -DDLIB_NO_GUI_SUPPORT=yes
--no DLIB_NO_GUI_SUPPORT: will set -DDLIB_NO_GUI_SUPPORT=no
Additional options:
--debug: makes a debug build
--cmake: path to specific cmake executable
--G or -G: name of a build system generator (equivalent of passing -G "name" to cmake)
