EDIT:

Tested this:



*# Google Protocol Buffers libraryINCLUDEPATH += 
"C:\\protobuf\\install\\include"LIBS += -L"C:\\protobuf\\install\\lib" 
-llibprotobuf*

And this one:



*# Google Protocol Buffers libraryINCLUDEPATH += 
"C:\\protobuf\\install\\include"LIBS += -L"C:\\protobuf\\install\\lib" 
-lprotobuf*


Same result over and over again.
