How to do it

These are the detailed steps to follow in CMakeLists.txt:

1. As in Recipe 8, Controlling compiler flags, we specify the minimum required version of CMake, project name, and language, and declare the geometry library target:

cmake_minimum_required(VERSION 3.5 FATAL_ERROR)project(recipe-10 LANGUAGES CXX)add_library(geometry  STATIC    geometry_circle.cpp    geometry_circle.hpp    geometry_polygon.cpp    geometry_polygon.hpp    geometry_rhombus.cpp    geometry_rhombus.hpp    geometry_square.cpp    geometry_square.hpp  )

2. We decide to compile the library with the -O3 compiler optimization level. This is set as a PRIVATE compiler option on the target:

target_compile_options(geometry  PRIVATE    -O3  )

3. Then, we generate a list of source files to be compiled with ...
