In which order did you built and install them? The order should be:
libmbim, libqmi, MM. This is so that libqmi is built with QMI over
MBIM support. You can run this to check whether that part is ok or
not:

$ cat /usr/include/libqmi-glib/qmi-version.h  | grep "define
QMI_MBIM_QMUX_SUPPORTED"
#define QMI_MBIM_QMUX_SUPPORTED 1
