## [main]
# Almost all CMake files should start with this
# You should always specify a range with the newest
# and oldest tested versions of CMake. This will ensure
# you pick up the best policies.
cmake_minimum_required(VERSION 3.1...3.16)
# This is your project statement. You should always list languages;
# Listing the version is nice here since it sets lots of useful variables
project(ModernCMakeExample VERSION 1.0 LANGUAGES CXX)
# If you set any CMAKE_ variables, that can go here.
# (But usually don't do this, except maybe for C++ standard)
# Find packages go here.
# You should usually split this into folders, but this is a simple example
# This is a "default" library, and will match the *** variable setting.
# Other common choices are STATIC, SHARED, and MODULE
# Including header files here helps IDEs but is not required.
# Output libname matches target name, with the usual extensions on your system
add_library(MyLibExample simple_lib.cpp simple_lib.hpp)
# Link each target with other targets or add options, etc.
# Adding something we can run - Output name matches target name
add_executable(MyExample simple_example.cpp)
# Make sure you link your targets with this command. It can also link libraries and
# even flags, so linking a target that does not exist will not give a configure-time error.
