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>
