CMake

ApplicationKitware

Dem still dey call am cmake gui, kitware cmake

KitwareProductivity

Kitware build-file generator. cmake.exe dey write Visual Studio or Ninja files. E no dey replace MSVC or rustc.

Wetin you need know

CMake dey generate build files. E no be compiler.

cmake.exe from Kitware dey write project files for Visual Studio, Ninja, and odas. cl.exe and link.exe still dey come from MSVC. rustc and go na different languages. To install CMake no dey install Visual Studio.

Wetin e be?: Build-file generator
E be compiler?: No. You still need MSVC or similar
E dey replace Visual Studio?: No. E fit generate .sln

Feex tok say

If cmake.exe configure and di compile fail, I go look di generator and di compiler wey e find. I no go treat CMake as MSVC. Di generator no be di toolchain.

Wetin be CMake?

CMake na meta-build system. E dey generate Visual Studio solutions, Ninja files, and odas. E no be cl.exe, no be rustc, and no be MSBuild itself.

If you never use am before

If C++ README talk say make you install CMake, get am from cmake.org/download. cmake.exe dey generate build files. E no be compiler. You still need MSVC, Ninja, or anoda toolchain. rustc.exe and go.exe na different languages. CMake no go replace devenv.exe.

Wetin dem dey use am for?

Generate Visual Studio solution

cmake -G "Visual Studio 17 2022". devenv.exe go con open dat .sln. CMake never compile am yet.

Ninja and oda generators

Ninja plus MSVC or GCC. cargo and go get dia own build graphs.

Presets

CMakePresets.json inside current projects. Dat file no be compiler binary.

Na who e dey for?

C and C++ developers wey dia repo dey start with CMakeLists.txt
People wey install CMake con dey wonder why cl.exe dey miss
Anybody wey think say CMake replace Visual Studio

Current status

CMake (2000) na current build generator from Kitware. Di vendor still dey point Windows users go https://cmake.org/download/.

How old e be?

Kitware release CMake for 2000 for large C++ trees. E old pass Rust and Go. Current 3.x/4.x releases na di product. Tutorial wey be 2.8-only fit miss modern presets.

System requirements

Values dey follow wetin di publisher release publicly. Workload still dey change di real need.

Minimum

Minimum system requirements
Operating system	Current 64-bit Windows 10 or Windows 11 release, based on Kitware
RAM	Di generator small. Di compile wey e dey start na di heavy step

Resource profile

CPU demand: Dey follow wetin you open inside di app
RAM demand: Dey follow documents, tabs, or libraries

Installed processes

Dese executables belong to dis product when e dey installed.

CMakeLists.txtCMakePresets.json

Common wahala dem

Configure succeed, compile fail

CMake find generator. Compiler or SDK still dey miss. Dat na MSVC or Windows SDK problem.

Wrong generator for di installed VS

"Visual Studio 17 2022" need VS 2022. CMake no fit invent devenv.exe.

How to get unstuck

cmake --version and where.exe cmake

Expect Program Files\CMake\bin. Any stray cmake.exe inside venv na different tori.

Install from cmake.org/download

Kitware dey host di MSI. Any CMake pack wey dem bundle with random compiler zip na junk.

Install Visual Studio or Build Tools if you want MSVC

Di Visual Studio Installer dey add cl.exe. CMake go con detect am.

Alternatives

Meson and Bazel na oda meta-build systems. MSBuild na wetin VS generator dey often target. CMake still na di common C++ front door.
