How to confirm libacars support? about acarsdec

[TLeconte]

"-- Using libacars" during Cmake tell you that acarsdec will use libacars.

You could use the Linux command ldd to be sure :
ldd ./acarsdec
it will list all linked lib.

On Fedora, libacars install in /usr/local/lib64, but it's true that libacars installation don't seem to be very automatic.

If libacars decodes something, it will output its dedicated "libacars" entry in the json message. ie :
