Notes on installing gpio-manager d-bus service from source

sudo make install does not do everyhing, so there are some extra steps:

• Create gpio-manager user or gpio groups.

  sudo useradd --system gpio-manager
  sudo groupadd --system gpio
  sudo usermod -aG gpio gpio-manager
  

sudo usermod -aG gpio $USER
