This simple C++ project supports compilation with CMake and Meson. (Autotool support could be added later on.) It's supposed to be used with oe-selftest.
An artificial project has several advantages over compiling a normal CMake or Meson based project for testing purposes: - It is much faster because it can be kept minimalistic - It can cover multiple odd corner cases - No one will change it in an unpredictable way - It can support multiple build tools with only one C++ codebase Signed-off-by: Adrian Freihofer <[email protected]> ---
