Could Not Find Boost (Missing: Unit_Test_Framework) (Found Version "1.71.0")

As Real Fresh suggested to use vcpkg mananger And So I gave it a try, I faced couple of issues but after that It worked so what I did is:

1.install vcpkg (Follow the instructions) You migh have the error when setting up (Fatal error, could not do post-extract operation renaming 'File' to 'Different name' ) You need to rename the manually.

2.install boost-test lib (you will see instruction on how to install packages) on the home page of vcpkg

3.you need to set these variables for cmake:

-DVCPKG_TARGET_TRIPLET=x86-windows (x86-windows in my case)
"-DCMAKE_TOOLCHAIN_FILE='root to vcpkg'/scripts/buildsystems/vcpkg.cmake" (in my case root to vcpkg = F:/Files/vcpkg
so the variable will be:
"-DCMAKE_TOOLCHAIN_FILE=F:/Files/vcpkg/scripts/buildsystems/vcpkg.cmake"

4.in your test/cmakelists.txt file you need to add the following:

find_package (Boost REQUIRED COMPONENTS unit_test_framework)
target_link_libraries (your_test_exe Boost::unit_test_framework)

in my case I have my test/cmakelists.txt like this:

cmake_minimum_required(VERSION 3.15)
project(My_String)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_FLAGS "--coverage" )
set(SOURCE_FILES MyStringTest.cpp)
set(Boost_DEBUG ON)

find_package (Boost REQUIRED COMPONENTS unit_test_framework)

include_directories(../Src)

add_executable (Boost_Tests_run ${SOURCE_FILES})

target_link_libraries (Boost_Tests_run Boost::unit_test_framework)

5.In your test.cpp you need to include:

#include <boost/test/included/unit_test.hpp> as it is!
in addition to the classes you are testing.

in my case it looks like this:

#define BOOST_TEST_DYN_LINK
#define BOOST_TEST_MAIN
#define BOOST_TEST_MODULE MyString_Test_Suite
#include
#include "MyString.h"
#include "MyString.cpp"
#include <boost/test/included/unit_test.hpp>

After more than a week of googling, trial and error this finally worked for me! Hope it helps if any one face the same issue. Thank you Real Fresh for your support!

I had resolved the same error message with apt-get install libboost-all-dev on my Ubuntu 20 machine.
