build on ubuntu

What environment variables do I set to build on Ubuntu?

$ cmake .
WSI: USE_PLATFORM_GLFW
Vulkan SDK path: /home/pem/vulkan/1.3.216.0
-- Using X11 for window creation
Vulkan include dir: VULKAN_INCLUDE-NOTFOUND
Vulkan libs: VULKAN_LIBRARY-NOTFOUND
-- Configuring done
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
VULKAN_INCLUDE
   used as include directory in directory /home/pem/pemcode/Hello_Triangle

edit I got progress when I did this:
export VULKAN_SDK=/home/pem/vulkan/1.3.216.0/x86_64

Yes, I prefer to rely on VULKAN_SDK. The SDK documentation how to set up the environment properly is here: https://vulkan.lunarg.com/doc/view/1.3.216.0/linux/getting_started.html#user-content-set-up-the-runtime-environment
