I can't compile my game for Android (cannot find -lwebsockets)

I have a question. I am trying to compile my game for android but this error always appears.

With iOS is working nice and I have tried in different computers. It appears if I try to compile the apk and if I just launch the game in my mobile phone. Last week was working, but suddenly this error started. I have been researching at the internet but I can’t find anything.

I’ll be grateful by any advice. Thank you!!
