Compile project Ubuntu

Hi,

When I'm compiling my project I'm receiving the following errors, do you have any idea?

CMakeFiles/black.dir/src/main.cpp.o: In function std::_Function_handler<void (cpp_redis::reply&), main::{lambda(cpp_redis::reply&)#2}>::_M_invoke(std::_Any_data const&, cpp_redis::reply&)': main.cpp:(.text+0x2d6): undefined reference to operator<<(std::ostream&, cpp_redis::reply const&)'
