CMake 快速入门教程 All In One

CMake

CMake is an open-source, cross-platform family of tools designed to build, test and package software.
CMake 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.
The suite of CMake tools were created by Kitware in response to the need for a powerful, cross-platform build environment for open-source projects such as ITK and VTK.

CMake 是一个开源的跨平台工具系列，旨在构建、测试和打包软件。
CMake 用于使用简单的平台和编译器独立配置文件来控制软件编译过程，并生成可在您选择的编译器环境中使用的本机 makefile 和工作区。
CMake 工具套件是由 Kitware 创建的，旨在响应 ITK 和 VTK 等开源项目对强大的跨平台构建环境的需求。

target_include_directories (Hello PUBLIC ${CMAKE_CURRENT_SOURCE_DIR})

CMakeLists.txt

# ???
# add_library (MATH_FUNCTIONS math_functions.c)
# add_library (math_functions math_functions.c)
# add_library (math_functions ./mf/math_functions.c)
// add_library (add ./mf/math_functions.c)

# ❌ 不好使呀
include_directories(mf)
include_directories(BEFORE mf ${CMAKE_CURRENT_SOURCE_DIR})
