How to add Local Sensor to Rasbeery Pi Gateway

[keldandorin]

Hi, need some help. I'd like to add a local sensor to my RPi gateway. In this case a DHT. when I try to compile my config I get a
examples_linux/mysgw.cpp:76:18: fatal error: DHT.h: No such file or directory
#include <DHT.h>
^
compilation terminated.
Makefile:114: recipe for target 'build/examples_linux/mysgw.o' failed
make: *** [build/examples_linux/mysgw.o] Error 1

I put the DHT.h and DHT.cpp in the Example_Linux folder.

Guess I'm doing this the wrong way, so need directions here.
Thx
