cmake – 找不到PROTOBUF编译器

我正在尝试用Caffe做一个CMake,但我的系统找不到protobuf编译器.我以前安装了protobuf2.7.0.现在我切换回2.6.1.如何配置我的CMake以识别protobuf2.6.1编译器？

我已经做好了

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

但是当我尝试cofke Caffe时,它仍然给我错误

以下命令对我有用.

apt-get install protobuf-compiler
