i, I setup the vulkan sdk environment exactly according to the instruction in gettin started guide (sorry can not post link):
In brief, I installed and verified ICD is present for my graphics card in one of the specified location.
Downloaded and untar-red the vulkan-sdk into root and used setup-env.sh to initialize env. Also including in bashrc to invoke it everytime.
THe above instruction in the URL had cpp and make build instruction using simple vulkan app, but today I am somehow unable to locate. I know I followed it exactly. Now instead I have some vague cmake simple app isntruction.
Anyways, I pasted the effort from yesterday below and problem is build error says vulkan.h is missing.
BELOW IS 1. CPP AND 2. MAKEFILE + 3. BUILD OUTPUT.
The build output complains glfw include statement unable to find <vulkan/vulkan.h> but I included that in the searchable path:
/root/vulkan/1.1.114.0/x86_64/include:/root/vulkan/1.1.114.0/x86_64/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/local/include/
Also makefile also some following statements:
CFLAGS = -std=c++17 -I$(VULKAN_SDK_PATH)/include
So why is it complaining about not finding the vulkan.h?

while(!glfwWindowShouldClose(window)) {
glfwPollEvents();
