My unsatiated need for autocomplete has lead me to this.

1. Replace the names, and maybe the kernel header path in CMakeLists.txt
2. Create a build directory. For example mkdir build
3. cd into the build directory
4. Run cmake ..
5. Run make. This should build the dummy library. From now on autocomplete should be working.
6. Run make module. This will build your module.
7. Happy hacking!

Shamelessly frankensteining these two resources:
