Also called cmake gui, kitware cmake

KitwareProductivity

Kitware's build-file generator. cmake.exe writes Visual Studio or Ninja files. It does not replace MSVC or rustc.

What you need to know

CMake generates build files. It is not a compiler.

cmake.exe from Kitware writes project files for Visual Studio, Ninja, and others. cl.exe and link.exe still come from MSVC. rustc and go are different languages. Installing CMake does not install Visual Studio.

What is it?: Build-file generator
Is it a compiler?: No. You still need MSVC or similar
Replaces Visual Studio?: No. It can generate a .sln

Feex says

If cmake.exe configures and the compile fails, I would look at the generator and the compiler it found. I would not treat CMake as MSVC. The generator is not the toolchain.

What is CMake?

CMake is a meta-build system. It generates Visual Studio solutions, Ninja files, and others. It is not cl.exe, not rustc, and not MSBuild itself.

If you have never used it

If a C++ README said install CMake, get it from cmake.org/download. cmake.exe generates build files. It is not a compiler. You still need MSVC, Ninja, or another toolchain. rustc.exe and go.exe are different languages. CMake will not replace devenv.exe.

What is it used for?

Generate a Visual Studio solution

cmake -G "Visual Studio 17 2022". devenv.exe then opens that .sln. CMake did not compile it yet.

Ninja and other generators

Ninja plus MSVC or GCC. cargo and go have their own build graphs.

Presets

CMakePresets.json in current projects. That file is not a compiler binary.

Who is it for?

C and C++ developers whose repo starts with CMakeLists.txt
People who installed CMake and wondered why cl.exe was missing
Anyone who thought CMake replaced Visual Studio

Current status

CMake (2000) is a current build generator from Kitware. The vendor still points Windows users at https://cmake.org/download/.

How old is it?

Kitware released CMake in 2000 for large C++ trees. It is older than Rust and Go. Current 3.x/4.x releases are the product. A 2.8-only tutorial may miss modern presets.

Versions

System requirements

Values follow the publisher's public guidance. Workload still changes the real need.

Minimum

Minimum system requirements
Operating system	A current 64-bit Windows 10 or Windows 11 release, per Kitware
RAM	The generator is small. The compile it starts is the heavy step

Resource profile

CPU demand: Follows what you open inside the app
RAM demand: Follows documents, tabs, or libraries

Installed processes

These executables belong to this product when it is installed.

Installed processes
cmake.exe	CMake command-line generator
cmake-gui.exe	Optional CMake GUI

Startup components

CMake does not start with Windows. You run it in a build folder.

File locations

Common CMake locations
Typical install	C:\Program Files\CMake\

File formats

CMakeLists.txtCMakePresets.json

Common problems

Configure succeeds, compile fails

CMake found a generator. The compiler or SDK is still missing. That is an MSVC or Windows SDK problem.

Wrong generator for the installed VS

"Visual Studio 17 2022" needs VS 2022. CMake cannot invent devenv.exe.

Getting unstuck

cmake --version and where.exe cmake

Expect Program Files\CMake\bin. A stray cmake.exe in a venv is a different story.

Install from cmake.org/download

Kitware hosts the MSI. A CMake pack bundled with a random compiler zip is junk.

Install Visual Studio or Build Tools if you wanted MSVC

The Visual Studio Installer adds cl.exe. CMake will then detect it.

Alternatives

Meson and Bazel are other meta-build systems. MSBuild is what a VS generator often targets. CMake is still the common C++ front door.

Official help and downloads

Configure is light. The compile you generate wants CPU and RAM.
