I don't remember exactly how yocto recipes are supposed to work; is it
that "if the modemanager package is included in build,
--with-modem-manager-1=yes is explicitly used"? Or is it that "if the
modemmanager config option in the networkmanager package is selected,
--with-modem-manager-1=yes is explicitly used"?

If you want to confirm, in any case, you can just look at the NM
package configure/build output, that will tell you whether MM support
is being correctly enabled or not.

If I'm not mistaken, you should see a "cdc-wdm0" device type "gsm"
once your modem is correctly detected by the MM+NM combo. That's why
I'm asking to confirm the build options used in NM.
