I am trying to install BlueZ as required by Zephyr, but when executing ./bootstrap-configure --disable-android --disable-midi it fails and gives this output:

Reading package lists... DoneBuilding dependency tree... DoneReading state information... Donecups is already the newest version (2.4.1op1-1ubuntu4.10).0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.A reinstall of cups didn't help either.
I searched on the system for 'cups.pc' but no matches were found, so I don't think the issue is configuring the PKG_CONFIG_PATH variable as the file does not even appear to exist. Any ideas on how to solve this?
I also have the error about ELL source is required or use --enable-external-ell, but that is completely unrelated to my understanding (and I haven't really looked into that as much).
