![]() ![]() CMake can be used to generate build files for build tools other than Make as well like Ninja, QtCreator, KDEvelop.Both CMake and Make does not have any user defined data types. CMake has 3 variables namely string, list and target with properties while Make has only one datatype that is string. Both CMake and Make are Turing Complete Programming Languages.So, if an library is removed after building, it will not be rebuilt by Make but CMake will take care of it. CMake tracks how a software was build while Make does not track it.In general, using CMake is easier for beginners compared to Make tool.On the other hand, Make tool is not actively maintained currently. Currently, CMake is actively maintained and new features are being developed. ![]() CMake has a support for Graphic User Interface (GUI) while Make does not have any GUI.CMake was developed in 2000 that is 24 years after Make. Make tool was developed in April 1976.CMake has a file "CMakeFile.txt" while Make tool has a file "Makefile".Recursive makefile means a top level makefile will invoke a makefile in a sub-project in a specific order. On the other hand, Make supports recursive makefiles of any level. Recursive Make files: CMake has a big limitation that it supports only well defined hierarchy of 3 levels without back loops.If the software aims to support only UNIX users as first preference, then Make is a good choice. So, if the software aims to support all users, then CMake is the best option. Make is for UNIX systems and is highly optimized but does not support portability across new devices. CMake is used to make the software portable across different systems like Windows, UNIX, embedded devices and much more as it can generate any build system that supports the system.So, CMake is an optional layer over Make. Make is a build system while CMake is a generator of build systems like Make and Ninja.The major differences between Make and CMake are: The steps with CMake are as follows: cmake -DLLVM_ENABLE_PROJECTS=clang -G "Unix Makefiles" It was in 2000 that CMake was introduced by Kitware which simplified the entire build process again. The complexity of the build process was increasing gradually. Developers attempted to simplify the process by using tools like automake, m4 and autoconf. Maintaining the configure and Makefile.in was complex and was a large file (sometimes, bigger than the actual source code). This worked well for some time but the problem grew bigger as the system variations became large. This involved a new file named Makefile.in which stored the configuration details and another script named configure which used the Makefile.in to update Makefile according to the system. The immediate solution was to set up a configuration script to customized the Makefile according to the current system. Developers had to edit the Makefile to compile the source code on a specific system. This came with a problem as the Makefile need different parameters for different systems. In 1976, software using Make to compile and run it had a Makefile and the steps to compile it were: makeĪs different systems started to emerged in the Industry, developers needed to compile the same source code in different systems. ![]() Make tool was developed in April 1976 by Bell Labs. We have presented a table summarizing the differences as well. ![]() In this article, we have explored the differences between Make and CMake in depth. ![]()
