I've built Suricata 4.1.4 as a package, and would like to use the magicfile option. As one of the many Suricata dependencies, I have +libmagic and the libraries are on the device under /usr/lib, but no .mgc file is installed.
Looking at the feeds/packages/libs/file/Makefile, it shows defines for installing files into /usr/share/magic but they don't seem to be being called.
