Quick Overview
CMake is a cross-platform, open-source build system generator. It is used to control the software compilation process using simple platform and compiler-independent configuration files, and generate native makefiles and workspaces that can be used in the compiler environment of your choice.
Pros
- Cross-platform compatibility, supporting a wide range of operating systems and compilers
- Highly flexible and extensible, allowing for complex build configurations
- Large and active community, providing extensive documentation and support
- Integrates well with various IDEs and development tools
Cons
- Steep learning curve for beginners
- Can be verbose and require more boilerplate code compared to some alternatives
- Performance can be slower for very large projects
- Some users find the syntax and structure less intuitive compared to other build systems
Code Examples
- Basic CMakeLists.txt for a simple project:
cmake_minimum_required(VERSION 3.10)
project(MyProject)
add_executable(MyExecutable main.cpp)
- Adding a library and linking it to an executable:
add_library(MyLibrary STATIC
src/library1.cpp
src/library2.cpp
)
add_executable(MyExecutable main.cpp)
target_link_libraries(MyExecutable PRIVATE MyLibrary)
- Setting compile options and definitions:
target_compile_features(MyTarget PRIVATE cxx_std_17)
target_compile_options(MyTarget PRIVATE -Wall -Wextra)
target_compile_definitions(MyTarget PRIVATE DEBUG_MODE)
Getting Started
- Install CMake from https://cmake.org/download/ or your system's package manager.
- Create a
CMakeLists.txt
file in your project root:
cmake_minimum_required(VERSION 3.10)
project(MyProject)
add_executable(MyExecutable main.cpp)
- Create a build directory and run CMake:
mkdir build && cd build
cmake ..
cmake --build .
- Run your executable:
./MyExecutable
Competitor Comparisons
C++ Library Manager for Windows, Linux, and MacOS
Pros of vcpkg
- Simplifies dependency management for C/C++ projects
- Supports cross-platform builds and multiple toolchains
- Integrates well with Visual Studio and other IDEs
Cons of vcpkg
- Limited to C and C++ libraries, while CMake supports multiple languages
- Requires more setup and configuration compared to CMake's built-in features
- Less mature and has a smaller community compared to CMake
Code Comparison
vcpkg
{
"name": "example",
"version-string": "1.0.0",
"dependencies": [
"boost",
"openssl"
]
}
CMake
cmake_minimum_required(VERSION 3.10)
project(example)
find_package(Boost REQUIRED)
find_package(OpenSSL REQUIRED)
Summary
vcpkg focuses on package management and dependency resolution for C/C++ projects, while CMake is a more comprehensive build system generator. vcpkg excels in simplifying library management, especially for Windows developers, but CMake offers broader language support and more mature build configuration options. Both tools can be used together in projects, with vcpkg handling dependencies and CMake managing the overall build process.
The Meson Build System
Pros of Meson
- Faster build times due to its optimized design and use of Ninja backend
- Simpler and more concise syntax, making build scripts easier to read and maintain
- Better cross-platform support, especially for Windows
Cons of Meson
- Smaller ecosystem and fewer available modules compared to CMake
- Less widespread adoption in large-scale projects
- Steeper learning curve for developers already familiar with CMake
Code Comparison
CMake example:
cmake_minimum_required(VERSION 3.10)
project(MyProject)
add_executable(myapp main.cpp)
target_link_libraries(myapp PRIVATE somelib)
Meson example:
project('MyProject', 'cpp')
executable('myapp', 'main.cpp', dependencies: dependency('somelib'))
Both CMake and Meson are popular build systems for C and C++ projects. CMake has been around longer and has wider adoption, especially in larger projects. It offers more flexibility and a vast ecosystem of modules. Meson, on the other hand, focuses on simplicity and speed, making it attractive for smaller to medium-sized projects and developers who prefer a more straightforward build system configuration.
a fast, scalable, multi-language and extensible build system
Pros of Bazel
- Faster build times for large projects due to advanced caching and parallelization
- Better support for multi-language projects and cross-platform builds
- More precise dependency management with fine-grained control
Cons of Bazel
- Steeper learning curve and more complex configuration
- Smaller ecosystem and community compared to CMake
- Less widespread adoption, especially in existing projects
Code Comparison
CMake example:
cmake_minimum_required(VERSION 3.10)
project(MyProject)
add_executable(MyApp main.cpp)
target_link_libraries(MyApp MyLib)
Bazel example:
cc_binary(
name = "MyApp",
srcs = ["main.cpp"],
deps = [":MyLib"],
)
Both CMake and Bazel are powerful build systems, but they have different strengths. CMake is more widely adopted and easier to learn, making it a good choice for many projects. Bazel, on the other hand, offers superior performance and scalability for large, complex projects, especially those involving multiple languages or platforms. The choice between the two depends on the specific needs of your project and team.
Premake
Pros of Premake
- Simpler syntax and easier to learn, using Lua scripting language
- More flexible and customizable build configurations
- Faster execution time for generating project files
Cons of Premake
- Smaller community and ecosystem compared to CMake
- Less widespread adoption in large-scale projects
- Limited built-in support for certain platforms and toolchains
Code Comparison
CMake example:
cmake_minimum_required(VERSION 3.10)
project(MyProject)
add_executable(MyApp main.cpp)
target_link_libraries(MyApp MyLibrary)
Premake example:
workspace "MyProject"
configurations { "Debug", "Release" }
project "MyApp"
kind "ConsoleApp"
language "C++"
files { "**.cpp", "**.h" }
links { "MyLibrary" }
Both CMake and Premake are popular build configuration tools, but they cater to different preferences and project needs. CMake offers a more extensive ecosystem and wider adoption, while Premake provides a simpler syntax and greater flexibility. The choice between the two often depends on project requirements, team expertise, and personal preference.

Supported Platforms
- Microsoft Windows
- Apple macOS
- Linux
- FreeBSD
- OpenBSD
- Solaris
- AIX
Other UNIX-like operating systems may work too out of the box, if not
it should not be a major problem to port CMake to this platform.
Please post to the CMake Discourse Forum
_ to ask if others have
had experience with the platform.

Building CMake with CMake
You can build CMake as any other project with a CMake-based build system: run an already-installed CMake on this source tree with your preferred generator and options. Then build it and install it.
To build the documentation, install Sphinx
_ and configure CMake with
-DSPHINX_HTML=ON
and/or -DSPHINX_MAN=ON
to enable the "html" or
"man" builder. Add -DSPHINX_EXECUTABLE=/path/to/sphinx-build
if the
tool is not found automatically.
To run the test suite, run ctest
in the CMake build directory after
building. See the CMake Testing Guide
_ for details.

Building CMake from Scratch
UNIX/Mac OSX/MinGW/MSYS/Cygwin ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
You need to have a C++ compiler (supporting C++11) and a make
installed.
Run the bootstrap
script you find in the source directory of CMake.
You can use the --help
option to see the supported options.
You may use the --prefix=<install_prefix>
option to specify a custom
installation directory for CMake. Once this has finished successfully,
run make
and make install
.
For example, if you simply want to build and install CMake from source, you can build directly in the source tree::
$ ./bootstrap && make && sudo make install
Or, if you plan to develop CMake or otherwise run the test suite, create a separate build tree::
$ mkdir build && cd build $ ../bootstrap && make
Windows ^^^^^^^
There are two ways for building CMake under Windows:
-
Compile with MSVC from VS 2015 or later. You need to download and install a binary release of CMake. You can get these releases from the
CMake Download Page
. Then proceed with the instructions above forBuilding CMake with CMake
. -
Bootstrap with MinGW under MSYS2. Download and install
MSYS2
_. Then install the required build tools::$ pacman -S --needed git base-devel mingw-w64-x86_64-gcc
and bootstrap as above.
.. _CMake Download Page
: https://cmake.org/download
.. _MSYS2
: https://www.msys2.org/
Reporting Bugs
If you have found a bug:
-
If you have a patch, please read the
