Comment:
from configure output:
```
-- Could NOT find PkgConfig (missing: PKG_CONFIG_EXECUTABLE) 
-- Configuring done
```
with `pkg-config` added to `hostmakedepends`:
```
-- Found PkgConfig: /usr/bin/pkg-config (found version "0.29.2") 
-- Checking for module 'systemd'
--   No package 'systemd' found
-- Configuring done
```
seems to not be fully necessary at the moment, but it would be good to add for future updates, in case upstream adds dependencies
