some help please?

and did you do what the error requested? To set VK_SDK_PATH or to pass VULKANSDK_LOCATION to CMake? — Cinder Biscuits
I actually didn't know how to do that. So how do I do it. Is it export VK_SDK_PATH=/path/to/vulkan/SDK. As suggested by ivan_onys — Rahul Gandharva
What version of Vulcan do you have installed? You will need to point it there and do as @ivan_onys stated, or you can pass it directly to CMake as cmake .. -DVULKAN_LOCATION=/path/to/Vulkan/SDK — Cinder Biscuits

Before running cmake, run the following command export VK_SDK_PATH=/path/to/vulkanSDK/version

Note, that is shall be full path (starting with /)

Be careful to run cmake .. from build folder. From the log, seems you start cmake from subfolder of the build folder. Better yet, clean it before reruning cmake:

cd build
rm -rf ./*
cmake ..
