Failed to build on Android NDK for arm arch

Hello. I tried to build vkmark for arm and faced this error:

That's weird.

Could you please check if VULKAN_HPP_HAS_SPACESHIP_OPERATOR is defined in your project (see in vulkan_hpp_macros.hpp, line 83)?
Do you have the "operators to compare vk::-handles"-section in your vulkan_handles.hpp? Which part is enabled there?
