# CMake (C / C++) (/examples/cmake)



Harmont has first-class CMake support. One `hm.cmake(...)` call picks the
compiler, passes cache `defines`, and gives you `test()`, `lint()`, and
`fmt()` actions backed by CTest and clang-format. This example uses an explicit
compiler and a Release build with C++20.
