To provide multiple paths in the CMAKE_PREFIX_PATH variable you need to delimit each entry by ;(semicolon). So your command will look like:

cmake -DCMAKE_PREFIX_PATH="C:\Qt\5.5\msvc2013\lib\cmake;C:\protobuf\src;C:\protobuf\c‌​make\build\Release"

To check if everything alright with the provided paths you can use the following code in the cmake file:

foreach(path ${CMAKE_PREFIX_PATH})
  message("Path: " ${path})
endforeach(path)

It will print every path provided.
