Introduction CMake is the de facto standard build system generator for C and C++ projects. Unlike traditional build systems (Make, Ninja, Visual Studio), CMake doesn’t build your code directly. Instead, it generates platform-native build scripts that compile and link your software reliably across Linux, macOS, Windows, and embedded systems. add_library(utils STATIC utils

add_library(utils STATIC utils.cpp) target_include_directories(utils PUBLIC include/private) # Both utils and my_app need it target_compile_definitions(utils PRIVATE UTILS_BUILD=1) add_executable(my_app main.cpp) target_link_libraries(my_app PRIVATE utils) # utils's PUBLIC includes propagate A master-level CMake project looks like this:

install(FILES "$CMAKE_CURRENT_BINARY_DIR/MyProjectConfigVersion.cmake" DESTINATION lib/cmake/MyProject ) CMake’s built-in testing is trivial to use: and embedded systems.
