CMake¶
CMake is a cross-platform build system generator. It is used to build, test, and package software. It is widely used in the open-source community and is used in many popular projects such as OpenCV, VTK, and ITK.
Installing CMake¶
To install CMake, you can download the installer from the official website: https://cmake.org/download/.
Using CMake¶
To use CMake, you need to create a CMakeLists.txt file in the root directory of your project. This file contains all the instructions for building your project.
Here is a basic example of a CMakeLists.txt file:
cmake_minimum_required(VERSION 3.10)
project(MyProject)
set(CMAKE_CXX_STANDARD 11)
add_executable(MyProject main.cpp)
In this example, we set the minimum required version of CMake to 3.10, set the project name to "MyProject", set the C++ standard to 11, and add an executable target called "MyProject" that compiles the "main.cpp" file.
To build the project, you can run the following command in the terminal:
cmake .
This will generate the necessary build files for your project in a directory called "build". You can then run the build process by running:
cmake --build .
This will build the project and create an executable file in the "build" directory. You can then run the executable to run your program.
