Therefore there have been significantly different approaches on how to write clean cmake files.
Of course this represents my opinion and experience and counter examples exist (boost comes to my mind).Ĭmake is an extremely powerful and feature rich tool which leaves a lot of decisions to the user. In spite of newer alternatives like Meson or Bazel, cmake has made it into the de-facto industry standard. In contrast, when using CMake, a CMakeLists.txt file is provided, which is used to create a Makefile. In the past autoconf, manually written Makefiles and others had been used but for the last decade the first choice has been cmake. In summary: The difference between CMake and Make is that Make creates executables from the source files, which have to include a Makefile. The first topic we’re going to talk about is the build system.
It can produce Makefiles, it can produce Ninja build files, it can produce KDEvelop or Xcode projects, it can produce Visual Studio solutions. In this post I try to sum up how I currently manage my C++ based projects with an in my opinion reasonable amount of effort.Īll samples I’m going to show can be found in this a repository with further comments within the scripts: github: conan-demo. 3 Answers Sorted by: 696 Make (or rather a Makefile) is a buildsystem - it drives the compiler and other build tools to build your code. Ever cloned a repository and had a really hard time to build the project? Chances are that the build scripts were over engineered or used a build system one was not familiar with. Can too much choice be a disadvantage? Build systems and dependency management for C++ sometimes might give the impression.
