Hello,everyone! When I run the following code to compile cartographer,I get the error that is make[2]: cpp_out: Command not found mkdir build cd build cmake .. make -j2

How should I solve it?

This means that PROTOBUF_PROTOC_EXECUTABLE is not being populated in your CMakeLists, do you have protobuf installed properly?
