Create a CMake-based project structure

[sisco0]

A folder structure must be created for the project. This folder structure would take into account that this project would be based on the use of CMake for managing building dependencies.

• Create main CMakeLists.txt file in the root folder of the project
• Modify the build system of dependencies for making them easily integrated into the CMake build system. This could be accomplished by creating CMakeLists.txt under the root folder of each dependency or by creating CMakeLists.txt.*.in files and including them to AquaMiner GPU CMakeLists.txt file
