I get 'vulkan/vulkan.h' file not found due to a different error on vulkan_core.h: vk_video/vulkan_video_codec_h264std.h' file not found after running a script using vulkan.h header file. The thing is that I have manually checked that the header file exists and that there's no typo
I have downloaded and set up latest vulkan sdk as recommended in the official documentation, following every step for my system (Fedora Linux). placing source of setup-env.sh in .bashrc, checked that every environment variable needed had a value (except VK_LAYER_PATH which i read that its not needed). And runned vkvia on the terminal successfully without any errors.
I check that everything works fine by running a test script which includes vulkan/vulkan.h header file. But basically, I get an error:
'vk_video/vulkan_video_codec_h264std.h' file not found
on vulkan-core.h l-8374 (#include "vk_video/vulkan_video_codec_h264std.h")
As I previously said, I manually checked that both vulkan/vulkan.h and vk_video/vulkan_video_codec_h264std.h exists.

Well, since it seems like I have to, and even though I dont know how you could reproduce the error on another system, I don't even know if it's vulkan's fault or mine, here's some additional info that you may want to know:
smallest script where the error happens (any with vulkan header file)
#include <vulkan/vulkan.h>
int main() {
return 0;
}
every error message I've gotten because of this
fatal error: 'vulkan/vulkan.h' file not found

Not sure whether we have the same cause of the problem, I will share my solution anyway:
Analysis: Following the error message, the parent folder of vulkan_core.h , the vulkan, is found to be in /usr/local/include, where no folder called vk_video can be loaded. This is caused by an incomplete cp provided by the official guidance: screenshot from vulkanSDK installation guide
Solution: Therefore, you might need to cp the vk_video folder togerther with the vulkan folder under your installation file 1.3.268.0/x86_64/include by this:
cd <your-folder>/1.3.268.0/x86_64/include
sudo cp -r vk_video/ /usr/local/include/
Then try to compile it again.
Hope it will help you and good luck with your program! (This is literally my first answer via this platform, please feel free to correct me if improperly behaved.)
