the way I used to to build libmbim for Ubuntu xenial is:
./autogen.sh

./configure --build=x86_64-linux-gnu --prefix=/usr --includedir=\${prefix}/include --mandir=\${prefix}/share/man --infodir=\${prefix}/share/info --sysconfdir=/etc --localstatedir=/var --disable-silent-rules --libdir=\${prefix}/lib/x86_64-linux-gnu --libexecdir=\${prefix}/lib/x86_64-linux-gnu --disable-maintainer-mode --disable-dependency-tracking --enable-gtk-doc --enable-gtk-doc-html --libexecdir=/usr/lib/libmbim

make; sudo make install

the needed patches of libqmi branch: qmi-1-12

libqmi need 17 patches[1] from qmi-1-16, 

One thing confuse me here is the version defined in configure.ac.
Because this backport include lots of patches and new interface (qmi-over-mbim), I'm not sure if it's better to sync the version as what qmi-1-16 is using.

No, the QMI over MBIM thing is not something we want to backport to older versions; as you have noticed you need a ton of patches backported and it really isn't worth it. I'm sorry you took the effort to do this but it just is cleaner to upgrade to a new version of the packages if needed.

If you want support for modems requiring FCC auth via QMI over MBIM in Xenial, you can always setup this PPA:
https://launchpad.net/~aleksander-m/+archive/ubuntu/modemmanager-xenial

Even for Trusty:

wow~ it's a bit sad to see comment 4 after I already comment 5. Anyway, thanks your information.

Like I said, sorry that you took all this time to do this, but it really isn't worth doing such a long backport; especially when you can just upgrade the versions to newer stable ones without incompatibilities. :/
