低版本protobuf與cmake問題:Could not find a package configuration file provided by "Protobuf" with any of the following names: ProtobufConfig.cmake

背景
如果使用Cmake編譯caffe, 且使用低版本protobuf(如2.5),會報錯cmake找不到protobuf。
解決思路:
更改caffe工程預設cmake檔案,使用pkg-config尋找。
解決辦法:
修改報錯的cmake檔案,路徑在caffe工程下cmake/ProtoBuf.cmake
, 修改如下兩處
