  It should be *very* simple.  See the examples in the other modules.

 Previously, I had a Makefile similar to this:

  Copy an "" from another module, and set the relevant flags.
Notice it's a *lot* simpler than before:

SRCS   = rlm_omapi.c
TGT_CFLAGS = -I/server/dhcp/server/include
TGT_LDFLAGS = -L/server/dhcp/server/lib -ldhcpctl -lomapi -ldns -lisc

  Yes.  We've completely re-done the build system.  It's very nice.

  We've gotten rid of libtool and libltdl completely.  Life is *much*
