This usually means that your header search paths are not configured properly. The header search paths should contain the C++ Standard Library headers before any C Standard Library, and you are probably using compiler flags that make that not be the case.

We don't need to introduce QNX_PYTHON_INSTALL_PATH (google doesn't know that anyway).
Just specify OPENCV_PYTHON_INSTALL_PATH value to CMake thorugh command-line or via cmake/OpenCVInstallLayout.cmake

Thanks, I removed this and passed OPENCV_PYTHON_INSTALL_PATH via toolchain.
