Summary:                    FindProtobuf module behavior under Windows is
annoying
Description: 
FindProtobuf module at the moment does not allow a Windows user to choose where
he has downloaded and built the ProtocolBuffer library. It forces the user to
choose by hand 4 variables: library, include, protoc library and protoc
executable.

If the user chooses a Release version of the built programs and libraries, then
try to build his project in Debug mode, he will receive the error:
_iterator_debug_level value '0' doesn't match value '2'

The module currently, thus, does not support multi-type build on Windows

Steps to Reproduce: 
- Build ProtocolBuffer
- Configure a project which uses ProtocolBuffer choosing the Release version
- Build the project in Debug 

Additional Information: 
Attached is the updated FindProtobuf.cmake which solves these issues. Under
Windows, there is a new variable: PROTOBUF_SRC_ROOT_FOLDER which will be used to
resolved the rest of the variables. The user only need to specify this variable
in order to have ProtocolBuffer detected.

Steps:
- Download ProtocolBuffer
- Build ProtocolBuffer with the supplied sln file
- Configure project which uses ProtocolBuffer
- Set PROTOBUF_SRC_ROOT_FOLDER to where one downloaded ProtocolBuffer
