Trouble with Abseil random

I'm trying to use some functions from ABSEIL random with Cmake. (like absl::Uniform()) I made all like in this instruction. And all work. Then i want more and started to test absl::Uniform(). ABSEIL RANDOM

My hello_word.cc is like

#include <iostream>
#include <string>
#include <vector>
#include "absl/strings/str_join.h"
#include "absl/random/random.h"


int main() {
  std::vector<std::string> v = {"foo","bar","baz"};
  std::string s = absl::StrJoin(v, "-");

  absl::BitGen bitgen;
  double fraction = absl::Uniform(bitgen, 0, 1.0);


  std::cout << "Joined string: " << s << "\n";
}

and CmakeLists.txt is:

cmake_minimum_required(VERSION 3.5)
project(my_project)

# Pick the C++ standard to compile with.
# Abseil currently supports C++11, C++14, and C++17.
set(CMAKE_CXX_STANDARD 11)

add_subdirectory(abseil-cpp)

add_executable(hello_world hello_world.cc)

target_link_libraries(hello_world absl::base absl::synchronization absl::strings)

And then cmake gives that:

And question: How to make it work? Thank you in advance.

Thank all.

I haven't seen here "Available Abseil CMake Public Targets" that for random shoud be absl::random_random

CMakeLists.txt should be like:

cmake_minimum_required(VERSION 3.5)
project(my_project)

# Pick the C++ standard to compile with.
# Abseil currently supports C++11, C++14, and C++17.
set(CMAKE_CXX_STANDARD 11)

add_subdirectory(abseil-cpp)

add_executable(hello_world hello_world.cc)
