Feng, thank you for your input. I have tried to use cmake to build protocol buffers but I get the same error when I use cmake.
If the syntax of the output is correct I believe the issue is the mixing of a forward slash "\" after the "C:" and then back slashes on the rest of the path, maybe. It is the only thing I can think of. I'll try removing the second libprotobuf.dll.a and issue the command on the command line to see if that works. Then I would have to fix either the makefile or the commands to the libtool.
