CMake构建Walnut项目时无法找到Vulkan头文件求助

我正在构建Walnut-cmake项目，使用Unix Makefiles生成器和MinGW工具链。执行make命令后出现编译错误：

D:/Projekty/C++/Walnut-cmake/Walnut/src/Walnut/Application.h:11:10: fatal error: vulkan/vulkan.h: No such file or directory    
11 | #include "vulkan/vulkan.h"       
   |          ^~~~~~~~~~~~~~~~~ compilation terminated.

Vulkan已正确安装并迁移到C盘默认路径（之前在D盘），我的CMakeLists.txt配置如下：

cmake_minimum_required(VERSION 3.0.0)
project(Walnut CXX)
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_EXTENSIONS OFF)

find_package(Vulkan REQUIRED)
message(STATUS "Found Vulkan: ${Vulkan_LIBRARIES}")
message(STATUS "Vulkan include dirs: ${Vulkan_INCLUDE_DIRS}")
find_package(OpenGL REQUIRED)

include_directories(${PROJECT_NAME} PRIVATE src/Walnut/ImGui ${Vulkan_INCLUDE_DIRS})

#print all include dirs for this project
get_property(dirs DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} PROPERTY INCLUDE_DIRECTORIES)
foreach(dir ${dirs})
message(STATUS "include dir='${dir}'")
endforeach()

file(GLOB_RECURSE ${PROJECT_NAME}_SRC
${CMAKE_CURRENT_SOURCE_DIR}/src/**.cpp
${CMAKE_CURRENT_SOURCE_DIR}/src/**.h
)

add_library(${PROJECT_NAME} ${${PROJECT_NAME}_SRC})
target_link_libraries(${PROJECT_NAME} PRIVATE ${Vulkan_LIBRARIES})

CMake输出显示已找到Vulkan且包含目录已正确添加：

-- Found Vulkan: C:/VulkanSDK/1.3.268.0/Lib/vulkan-1.lib
-- Vulkan include dirs: C:/VulkanSDK/1.3.268.0/Include

-- include dir='D:/Projekty/C++/Walnut-cmake/Walnut/src'
-- include dir='D:/Projekty/C++/Walnut-cmake/vendor/stb_image'
-- include dir='D:/Projekty/C++/Walnut-cmake/vendor/imgui'
-- include dir='D:/Projekty/C++/Walnut-cmake/vendor/glfw/include'
-- include dir='D:/Projekty/C++/Walnut-cmake/Walnut/Walnut'
-- include dir='D:/Projekty/C++/Walnut-cmake/Walnut/PRIVATE'
-- include dir='D:/Projekty/C++/Walnut-cmake/Walnut/src/Walnut/ImGui'
-- include dir='C:/VulkanSDK/1.3.268.0/Include'

即使手动指定vulkan.h路径，编译仍然失败，求解决办法。

1. 修复CMake包含目录配置 #

你当前使用的include_directories用法错误（第一个参数不应是目标名），且全局配置容易引发冲突。改用目标专属的包含目录设置，确保Vulkan路径只作用于Walnut库：

# 删除原来的include_directories行，替换为：
target_include_directories(${PROJECT_NAME} 
    PRIVATE 
        src/Walnut/ImGui 
        ${Vulkan_INCLUDE_DIRS}
)

2. 验证MinGW与Vulkan SDK的兼容性 #

Vulkan SDK默认提供MSVC适配的库，但MinGW需要对应环境的文件：

• 确认C:/VulkanSDK/1.3.268.0/Include/vulkan/vulkan.h确实存在
• 如果SDK没有MinGW专用库，可通过MSYS2包管理器安装mingw-w64-x86_64-vulkan（提供适配MinGW的头文件和静态库）

3. 彻底清理旧构建缓存 #

之前Vulkan在D盘的配置缓存可能残留，按以下步骤操作：

1. 删除项目的build目录
2. 重新运行CMake生成命令（明确指定MinGW工具链）：

   cmake -G "Unix Makefiles" -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++ ..
   

3. 再次执行make

4. 检查编译命令中的包含路径 #

查看make输出的完整编译指令，确认-IC:/VulkanSDK/1.3.268.0/Include是否存在。如果缺失，可在CMake中强制添加：

target_compile_options(${PROJECT_NAME} PRIVATE -IC:/VulkanSDK/1.3.268.0/Include)

5. 调整头文件引用方式 #

将代码中的#include "vulkan/vulkan.h"改为#include <vulkan/vulkan.h>，让编译器从指定的系统包含目录中查找，而非当前文件所在目录。
