I'm trying to include vulkan hpp library using cmake with fetch_content (I want to automate this and I don't want the user to manually install vulkan, if this is a wrong approach let me know because I'm just starting with cmake) as shown in the following code snippet...

The repository you specified does not actually contain the Vulkan headers. Use this instead. It provides a
CMakeLists.txt file which adds the headers to a library called
Vulkan::Headers so you can just add the subdirectory and then link to them using
target_link_libraries(example PRIVATE Vulkan::Headers).
But why would you do this? To use Vulkan you have to have the Vulkan SDK installed (the actual libraries) and the SDK also includes the headers.
1st of all I rewrote the Vulkan tutorial triangle in vulkan-hpp with unique handles. When closing the program i got the following assertion:
Assertion: m_dispatch && m_owner Looking at the code, I found out enabling VULKAN_HPP_NO_EXCEPTIONS would fix it but now I get this error:
vk::UniqueHandle &vk::UniqueHandle::operator =(const vk::UniqueHandle &)': attempting to reference a deleted function

This seems to work for me:
I'm developping a game engine using vulkan and glfw. As indicated here, with glfw there's a bunch of macros to include OpenGL/OpenGL ES/Vulkan. Since it is now included in the vulkan sdk, how can I setup glfw to include vulkan-hpp. Do I just need to put GLFW_INCLUDE_NONE and add
#include or do I need to implement something else?
ANSWERAnswered 2021-Jan-15 at 19:37
If we take a look at
GLFW.h, it just includes
vulkan.h only if the
GLFW_INCLUDE_VULKAN macro is defined. So if you want to include the
vulkan.hpp file, just undefine the
GLFW_INCLUDE_VULKAN macro and include the file explicitly.
GLFW is a C library.
vulkan.hpp file contains C++ stuff inside so there could be compatibility issues. That's why GLFW only includes
vulkan.h and not
Where I can find C++ specification for Vulkan (same like the official C one on Khornos pages), describing the particular Vulkan api primitives and functions? Does it even exist (I was trying to find it with no success)?
Personaly I am using the C api even with C++ as I already got used to its style and it fits my needs perfectly (verbose, but you see everything), but I have to go through the code written by other people using C++ api. Usually Vulkan C++ api is just some syntactic sugar build upon the C api function calls, but sometimes digging through vulkan.hpp and trying to figure out what is going on is really annoying.
I am aware of this: https://github.com/KhronosGroup/Vulkan-Hpp...

There is no "Vulkan C++ specification". There's a header file containing some functions and types that make using Vulkan more C++-friendly. But those are not part of any actual specification.
The mapping from "VulkanHpp" into regular C Vulkan is pretty obvious in most cases and can be deduced just from the nature of the APIs in question.
vk::ImageCreateInfo means the same thing, with the same fields, as
VkImageCreateInfo as defined by the Vulkan specification. The C++ wrapper is not trying to confuse users as to how it works.

This is caused by the
vulkan.hpp C++ header. It assumes that all functions are present, which is not the case for extension functions (that aren't part of the core). So you need to pass a dynamic dispatcher to the messenger callback creation function.
I'm not using
vulkan.hpp myself, but it should look something like this in your case:
I have been having a look into the vulkan-hpp source code to try to understand how to manage
StructureChains. I've found this odd looking syntax (line marked with comment) related with the usage of
template keyword as a member type. Moreover, its followed by a function call with no
ANSWERAnswered 2020-Feb-03 at 14:26
template keyword is used to disambiguate the following expression as a template instantiation.
structureChain type depends on template parameters, so the compiler cannot know how to interpret the following
get expression, which may be an instantiation of a
get template, or comparison expression. The
template keyword indicates that
get is a template, and the following is a template instantiation. In the absence of this keyword the compiler would assume
get is not a template, so the following must be a comparison expression.
