packages can use find_package(PythonInterp REQUIRED) find_package(PythonLibs REQUIRED) while we control PYTHON pointing to native py3 the libs and include directories will then point to build host version, which can result in unexpected combination and if we are lucky we get errors if its quite different e.g. py2 libs/includes and py3 executable This variable can be then used to export PYTHON_LIBRARY and PYTHON_INCLUDE_DIR so that above find_packages can work correctly see [1] for how it happens in cmake LLDB uses it see [2] [1] https://github.com/Kitware/CMake/blob/master/Modules/FindPythonLibs.cmake [2] https://github.com/llvm/llvm-project/blob/master/lldb/cmake/modules/LLDBConfig.cmake#L226 (From OE-Core rev: e45c06fe6f9a21c2cd06ae003cb112556382f81e) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
