[PATCH v2 08/14] meson: Link with libinotify on FreeBSD
Posted by Alex Bennée 9 months, 3 weeks ago
From: Ilya Leoshkevich <iii@linux.ibm.com>

make vm-build-freebsd fails with:

    ld: error: undefined symbol: inotify_init1
    >>> referenced by filemonitor-inotify.c:183 (../src/util/filemonitor-inotify.c:183)
    >>>               util_filemonitor-inotify.c.o:(qemu_file_monitor_new) in archive libqemuutil.a

On FreeBSD the inotify functions are defined in libinotify.so. Add it
to the dependencies.
