Sierra Wireless EM7455

[Stefan Armbruster]

pkg-config --modversion mbim-glib returns 1.12.2.

# find /usr -name "libmbim*.so"
/usr/lib/libmbim-glib.so
/usr/lib/x86_64-linux-gnu/libmbim-glib.so

So my build from git gets installed to /usr/lib and the the one in
/usr/lib/x86_64-linux-gnu/ is from the Ubuntu packages archive.

How to deal with that? I see generally 3 options:
1) get rid of installed ubuntu packages - but modemmanager depends on those
2) change precedence of /usr/lib over /usr/lib/x86_64-linux-gnu
3) change ./configure in libmbim /libqmi build to overwrite the
existing lib in /usr/lib/x86_64-linux-gnu/

I guess 3 is the way to go. What options do I need to set on ./configure ?

Cheers,
Stefan
