How to do it

These are the steps to follow to build our project using Boost test:

1. We start out with the now familiar CMakeLists.txt structure:

# set minimum cmake versioncmake_minimum_required(VERSION 3.5 FATAL_ERROR)# project name and languageproject(recipe-04 LANGUAGES CXX)# require C++11set(CMAKE_CXX_STANDARD 11)set(CMAKE_CXX_EXTENSIONS OFF)set(CMAKE_CXX_STANDARD_REQUIRED ON)# example libraryadd_library(sum_integers sum_integers.cpp)# main codeadd_executable(sum_up main.cpp)target_link_libraries(sum_up sum_integers)

2. We detect the Boost library and link cpp_test against it:

find_package(Boost 1.54 REQUIRED COMPONENTS unit_test_framework)add_executable(cpp_test test.cpp)target_link_libraries(cpp_test  PRIVATE    sum_integers Boost::unit_test_framework ...
