A simple hello world kernel module, that can be build with cmake. Utilize Kbuild through cmake, and do it in a build directory.
Usage:
- clone it.
- create a folder: mkdir build
- navigate into build: cd build
- run cmake: cmake ../
- build it: make
Expected behavior:
cmake ../ shall do:
$ cmake ../
