meson: Fix local meson build

Currently local meson build fails because some sources require cereal
and it is not even listed in the meson dependencies.
To fix the issue add cereal to the dependencies list and provide a wrap
file for the local build.

Tested:
"meson setup build && cd build && meson compile" finishes successfully.
