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 (From OE-Core rev: 4904e772470b0d6e5d98ef0344b3f2bf54214661) Signed-off-by: Adrian Freihofer <adrian.freihofer@siemens.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
