Sergey Sharybin d3c3f07133 Initial implementation of a script for automatic dependencies installer/builder
This script will install all packages from the repositories and will compile
missing in repositories libraries.

It is supposed to replace pre-compiled libraries from our svn.

Tested script on Fedora 14 and 17, Ubuntu 10.04 and 12.10. All the dependencies
and manually built libraries seems to be fine. However, it's really annoying to
build blender in virtual machine to ensure there's no linking errors, i would
hope community will help testing and making needed tweaks to the script :)

To use the script, simple run it from your user name. It'll run installation
commands from a sudo, so you would likely be requested to type a password.

I've made tweaks to CMake FindLibs, so it should find OIIO, OCIO and python
libraries compiled by this script. Boost and FFmpeg would need to be specified
manually.

SCons currently would require manual paths specifications as well. Perhaps we
could make SCons smarter in the future.

All the parameters you need to pass to CMake/SCons would be printed when script
finishes to run.

Pretty much sure it's not production-ready script, but we need to start testing
at some point :)

# - Find Python libraries
# Find the native Python includes and library
#
# Note:, This is not _yet_ intended to be a general python module for other
# projects to use since its hard coded to python 3.2 as blender only supports
# a single python version.
# This is for blender/unix python only.
#
# This module defines
# PYTHON_VERSION
# PYTHON_INCLUDE_DIRS
# PYTHON_INCLUDE_CONFIG_DIRS
# PYTHON_LIBRARIES
# PYTHON_LIBPATH, Used for installation
# PYTHON_LINKFLAGS
# PYTHON_ROOT_DIR, The base directory to search for Python.
# This can also be an environment variable.
#
# also defined, but not for general use are
# PYTHON_LIBRARY, where to find the python library.
