How to solve the problem of adding Boost when configuring cmake?

Question

C++ / C#

Hi all.
I'm trying to connect the boost asio libraries to my project. But I encounter a problem when configuring
Imported targets and dependency information not available for Boost version
Googled this problem for two days, but I could not solve it. I'm just getting started with C++.
New cmake warning about BOOST
CMake finds Boost but the imported targets not ava...
Understood that Boost 1.65 and 1.65.1 require CMake 3.9.3 or newer. However, updating cmake to 3.12.1 gives no results.
Please help or advice on this matter.
System: Ubuntu 18.04
libboost: 1.65.1.0ubuntu1
cmake version 3.12.1 (updated)
Simple project code

#include <iostream>
#include <boost/asio.hpp>

int main() {
    std::cout << "Hello, World!" << std::endl;

    boost::asio::ip::tcp::iostream stream("google.com", "http");
    stream << "GET /ip HTTP/1.1\r\nHost: google.com\r\nConnection: closer\n\r\n";
    std::cout << stream.rdbuf();
    
    return 0;
}

CMakeList.txt

cmake_minimum_required(VERSION 3.12)
project(ticker)

set(CMAKE_CXX_STANDARD 11)

set (BOOST_ROOT "/usr/lib/x86_64-linux-gnu/")

set (Boost_NO_SYSTEM_PATHS ON)
set (Boost_USE_MULTITHREADED ON)
set (Boost_USE_STATIC_LIBS ON)
set (Boost_USE_STATIC_RUNTIME OFF)
set (BOOST_ALL_DYN_LINK OFF)

find_package (Boost REQUIRED COMPONENTS system filesystem)

if (Boost_FOUND)
    include_directories (SYSTEM ${Boost_INCLUDE_DIR})
endif ()

add_executable(ticker main.cpp)

target_link_libraries (ticker ${Boost_LIBRARIES})

When I try to compile I get the following

cmake ticker

All you need to write:

find_package(Boost 1.65.1 REQUIRED)

# ...

include_directories(SYSTEM ${Boost_INCLUDE_DIRS})

# ...

target_link_libraries(myapp ${Boost_LIBRARIES})

Remove everything else related to boost until you understand why it is needed. And don't forget to install boost-dev or boost-devel or libboost-all-dev, I don't remember exactly what it's called in Ubuntu, on the system.
