CMake.org is the official website of CMake, an open-source cross-platform build system. The website serves as a central hub for all information related to CMake, providing comprehensive documentation, tutorials, and resources for developers. It highlights the key features and benefits of CMake, including its support for a wide range of programming languages and platforms, its modular and extensible design, and its ability to generate build scripts for various build systems. The website also offers downloads for the latest CMake releases, as well as a community page where users can seek help, join discussions, and contribute to the development of CMake.

When you create a new project, CLion generates CMakeLists.txt file automatically and places it in the project root directory. Example below shows the CMakeLists.txt file of a simple "Hello, World!"jetbrains.comCMakeLists.txt file contains a set of directives and instructions describing the project's source files and targets (executable, library, or both).

A number of useful variables are automatically defined by CMake and are discussed in the cmake-variables manual. These variables begin with CMAKE_. Use the set command to set variable values.cmake.orgCMakeLists files use variables much like any programming language. CMake variable names are case sensitive and may only contain alphanumeric characters and underscores.

In the main Makefile you will find only the PHONY rules for your CMake targets. The only exception I know of is the Ninja Makefiles generator which puts all build rules into single file. 1. 2. 3. 4.stackoverflow.comCMake's documentation is unclear here. The Makefiles generators of CMake do create the source file make rules in sub Makefiles which are not visible in the main Makefile.
