Error compiling Mosquitto 1.4.8 with libwebsockets

Question

After I installed libwebsockets 1.4, I wanted to make Mosquitto 1.4.8 run witch Websockets. But when I compile I get some Errors:

user@Mate:~/Dokumente/mosquitto-1.4.8$ make

set -e; for d in lib client src; do make -C ${d}; done

Information: I tested Mosquitto two days before without Websockets and it worked well but when I want to compile it again (no matter if I choose Websockets or not) I get these Errors.

Looks like your websocket library is not correctly installed.

Try it :

sudo apt-get install libwebsockets-dev
