Problems when using Modules

[Chery-cake]

When trying to use modules i get a list of errors and warnings like this:

/build/_deps/_vma_hpp-src/VulkanMemoryAllocator/include/vk_mem_alloc.h:16533:18: warning: pointer is missing a nullability type specifier (_Nonnull, _Nullable, or _Null_unspecified) [-Wnullability-completeness]

Changing the module declaration from this:

// Generated from the Vulkan Memory Allocator (vk_mem_alloc.h).
module;
#define VMA_HPP_CXX_MODULE
#define VMA_IMPLEMENTATION
#include "vk_mem_alloc.hpp"
#include "vk_mem_alloc_raii.hpp"
export module vk_mem_alloc;
export import vulkan;

to this:

// Generated from the Vulkan Memory Allocator (vk_mem_alloc.h).
module;
#include "vk_mem_alloc.hpp"
#include "vk_mem_alloc_raii.hpp"
export module vk_mem_alloc;
export import vulkan;
#define VMA_HPP_CXX_MODULE
#define VMA_IMPLEMENTATION

Solves all the problems.

I'm using clang 22.1.5 on linux.

This is my cmake config to import the library:

FetchContent_Declare(
    _vma_hpp
    GIT_REPOSITORY https://github.com/YaaZ/VulkanMemoryAllocator-Hpp.git
    GIT_TAG v3.3.0+3
    GIT_SHALLOW TRUE
)
set(VMA_STATIC_VULKAN_FUNCTIONS OFF CACHE BOOL "" FORCE)
set(VMA_DYNAMIC_VULKAN_FUNCTIONS ON CACHE BOOL "" FORCE)
FetchContent_MakeAvailable(_vma_hpp)

add_library(vma INTERFACE)
target_link_libraries(vma INTERFACE
  vulkan
  VulkanMemoryAllocator-Hpp::VulkanMemoryAllocator-Hpp
  VulkanMemoryAllocator-Hpp::VulkanMemoryAllocator-HppModule
)
target_compile_definitions(vma INTERFACE
    VULKAN_HPP_DISPATCH_LOADER_DYNAMIC=1
    VMA_STATIC_VULKAN_FUNCTIONS=0
    VMA_DYNAMIC_VULKAN_FUNCTIONS=1
)
set_target_properties(vma PROPERTIES
    POSITION_INDEPENDENT_CODE ON
    CXX_VISIBILITY_PRESET default
    VISIBILITY_INLINES_HIDDEN OFF
    WINDOWS_EXPORT_ALL_SYMBOLS ON
    CXX_MODULE_STD ON
