   4 The commit changed the detection path due to FreeBSD issues,
   5 but apparently affects also Openwrt buildroot negatively.

   7 Original explanation:
   8   From 6124da7a48f28f54fc09ebeb942d1037516fe6ab Mon Sep 17 00:00:00 2001
   9   Subject: [PATCH] Fix libmodbus detection on FreeBSD
  10
  11   We look for modbus/modbus.h in /usr/local/include/modbus
  12   but we should look for modbus.h
  13
  14   This is only an issue on FreeBSD since /usr/local/include is not
  15   in the default search path.
