OBS CMake build framework 3.0 is a minor overhaul of version 2.0. Due to close proximity of the 2.0 rework, the amount of actual changes to project files are minimal and mostly concern application generation. This commit contains the bootstrap elements only and requires OS-specific implementations to be functional.
