If I don't set
CONFIGURE_ARGS += "LIBS=-L/usr/local/lib -lmagic"
make test fails. I need both of them, -L and -l.

They seem to store the required libraries and paths in
/usr/local/libdata/perl5/site_perl/amd64-openbsd/auto/File/LibMagic/LibMagic.so
so the dynamic loader finds the dependent library automatically.

With this hardcoded patch, I can build the module.

This module requires the libmagic.so library and magic.h header. See
Show quoted text> Also, I don't suppose that libmagic uses pkg-config. C::AC can use that to find the necessary flags.
I have never used pkg-config.
