This PR introduces the following:

• Unification of the CMakeLists.txt script for all native libraries inside the framework.
• Decomposition and association of sources, dependencies, headers, and toolchain compilers with the main CMakeLists.txt using shell scripting.
• Android-NDK downloading and setup task.
• Android-NDK and NDK headers associating script for building to android targets.

This considered to be the initiative to support android and arm toolchains and any other foreign toolchain, it will be merged as it is for now, knowing that there should be also a support for linking directories (the functionality of -L{dir} argument) for the auto linkable libraries.
