I'm trying to do a CMake with Caffe, but my system cannot find protobuf compiler. I have previously installed protobuf2.7.0. Now I switched back to 2.6.1. How could I configure my CMake to recognize the protobuf2.6.1 compiler?

I have done 

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

But when I try to cmake Caffe, it still gives me the error 

user@user-computer:~/caffe/build$ cmake -DBLAS=open ..

The following command worked for me.

 apt-get install protobuf-compiler

    Problem solved. I need to remove the whole build directory I compiled before. And, recreate the build directory and do the cmake -DBLAS=open .. again. Then, it will be able to find the protobuf-compiler – holopekochan Oct 24 '17 at 19:00

I meet the same problem. I solved it by running following commands：

sudo apt-get remove protobuf-compiler
sudo apt-get install protobuf-compiler

I had tried to run just the second command, but it doesn't work.
