找不到PROTOBUF编译器。我做了apt-get install protobuf-compiler

Question

我用相同的标题查看了另一个问题，无法解决我的问题。我也做了

$ sudo apt-get install  libprotobuf-dev protobuf-compiler
$ protoc --version
libprotoc 2.6.1

当我这样做时

sudo make -j4 && make pycaffe

我得到了

CMake Error at cmake/ProtoBuf.cmake:13 (message):
  Could not find PROTOBUF Compiler
Call Stack (most recent call first):
  cmake/Dependencies.cmake:24 (include)
  CMakeLists.txt:46 (include)

@ chan3600建议我删除构建目录。我没有构建目录。请告诉我如何解决这个问题。
