![]() ![]() It can also link libraries and # even flags, so linking a target that does not exist will not give a configure-time error. ![]() # Make sure you link your targets with this command. # Adding something we can run - Output name matches target name add_executable(MyExample simple_example.cpp) ![]() ![]() # Link each target with other targets or add options, etc. # Output libname matches target name, with the usual extensions on your system add_library(MyLibExample simple_lib.cpp simple_lib.hpp) # Other common choices are STATIC, SHARED, and MODULE # Including header files here helps IDEs but is not required. # You should usually split this into folders, but this is a simple example # This is a "default" library, and will match the *** variable setting. # (But usually don't do this, except maybe for C++ standard) # Find packages go here. # If you set any CMAKE_ variables, that can go here. You should always list languages # Listing the version is nice here since it sets lots of useful variables project( This will ensure # you pick up the best policies. # Almost all CMake files should start with this # You should always specify a range with the newest # and oldest tested versions of CMake. For this program, we have one library (MyLibExample) with a header file and a source file,Īnd one application, MyExample, with one source file. If you're interested in becoming a professional build engineer, a better software developer, or simply want to become proficient with CMake, if you'd like to understand how projects come together and why, if you're transitioning from a different build environment, or if you're interested in learning modern CMake from the ground up, then this book is for you.This is a simple yet complete example of a proper CMakeLists. Learning the C++ language often isn't enough to prepare you for delivering projects to the highest standards. After completing this book, you'll be able to use CMake confidently on a professional level. Finally, you'll explore how to export, install, and package your solution for internal and external purposes. You'll also understand how to add external dependencies to the project: third-party libraries, testing frameworks, program analysis tools, and documentation generators. As you progress, you will learn how to compile and link executables and libraries, how these processes work in detail, and how to optimize all steps to achieve the best results. The book instructs you on how to form the source directories, as well as build targets and packages. It guides you through the automation of complex tasks appearing in many projects, including building, testing, and packaging. It teaches you how to use CMake in your CMake projects, and also shows you what makes them maintainable, elegant, and clean. Modern CMake for C++ is an end-to-end guide offering a simpler experience, as it treats building C++ solutions in a comprehensive manner. At the same time, most resources explain this process chaotically, without the proper background, context, and structure. Developers researching this subject online frequently have problems determining which advice is up to date and which approaches have already been superseded by fresher, better practices. Creating top-notch software isn't an easy task. ![]()
