Subject: Fix libmodbus detection on FreeBSD
X-Git-Tag: collectd-5.5.1~71^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6124da7a48f28f54fc09ebeb942d1037516fe6ab;p=thirdparty%2Fcollectd.git

Fix libmodbus detection on FreeBSD

We look for modbus/modbus.h in /usr/local/include/modbus
but we should look for modbus.h

This is only an issue on FreeBSD since /usr/local/include is not
in the default search path.
