I am not able to install the Library . I am getting Error
Invalid library found in C:\Documents and Settings\User\My Documents\Arduino\libraries\ESP8266MQTTMesh: C:\Documents and Settings\User\My Documents\Arduino\libraries\ESP8266MQTTMesh.

I changed the name of the zipped file to ESP8266MQTTMesh as the name of .cpp file ESP8266MQTTMesh.cpp. Still it is saying Invalid Library found in ....
What could be the problem.
