Use target_include_directory

* Fwk: Avoid use of include_directories
* Remove target_include_directories from Commands
* Refactor cmake includes
- Avoid using include_directories, and use target_include_directories.
- Use add_subdirectory directly from main cmakefile, do not use in ApplicationLibCode.
