premake修改：

GLFW下的premake：

Lua 复制代码 
project "GLFW"
	kind "StaticLib"
	language "C"
	staticruntime "on"
	warnings "off"

	targetdir ("bin/" .. outputdir .. "/%{prj.name}")
	objdir ("bin-int/" .. outputdir .. "/%{prj.name}")

	files
	{
		"include/GLFW/glfw3.h",
		"include/GLFW/glfw3native.h",

	}

	filter "system:linux"

	filter "system:macosx"

		}

		defines 
		{ 
			"_GLFW_WIN32",
			"_CRT_SECURE_NO_WARNINGS"
		}

	filter "configurations:Debug"
		defines "YT_DEBUG"
		buildoptions "/MTd"
		symbols "On"
	

	filter { "system:windows", "configurations:Debug-AS" }	
		runtime "Debug"
		symbols "on"
		sanitize { "Address" }
		flags { "NoRuntimeChecks", "NoIncrementalLink" }

	filter "configurations:Release"
		defines "YT_RELEASE"
		buildoptions "/MT"
		symbols "On"

		filter "configurations:Dist"
		defines "YT_DIST"
		buildoptions "/MT"
		symbols "On"

Glad下的premake：

Lua 复制代码 
project "Glad"
	kind "StaticLib"
	language "C"
	staticruntime "on"
	warnings "off"

	targetdir ("bin/" .. outputdir .. "/%{prj.name}")
	objdir ("bin-int/" .. outputdir .. "/%{prj.name}")

	files
	{
		"include/glad/glad.h",
		"include/KHR/khrplatform.h",
		"src/glad.c"
	}

	includedirs{
		"include"-- 为了glad.c直接#include <glad/glad.h>，而不用#include <include/glad/glad.h
	}
	filter "system:windows"
		systemversion "latest"

	
	filter { "system:windows", "configurations:Debug-AS" }	
		runtime "Debug"
		symbols "on"
		sanitize { "Address" }
		flags { "NoRuntimeChecks", "NoIncrementalLink" }

	filter "configurations:Debug"
		defines "YT_DEBUG"
		buildoptions "/MTd"
		symbols "On"

	filter "configurations:Release"
		defines "YT_RELEASE"
		buildoptions "/MT"
		symbols "On"

		filter "configurations:Dist"
		defines "YT_DIST"
		buildoptions "/MT"
		symbols "On"

ImGui下的premake:

Lua 复制代码 
project "ImGui"
	kind "StaticLib"
	language "C++"
	cppdialect "C++17"
    staticruntime "on"

	targetdir ("bin/" .. outputdir .. "/%{prj.name}")
	objdir ("bin-int/" .. outputdir .. "/%{prj.name}")
	defines { "IMGUI_API=__declspec(dllexport)" }
	files
	{
		"imconfig.h",
		"imgui.h",
		"imgui.cpp",
		"imgui_draw.cpp",
		"imgui_internal.h",
		"imgui_tables.cpp",
		"imgui_widgets.cpp",
		"imstb_rectpack.h",
		"imstb_textedit.h",
		"imstb_truetype.h",
		"imgui_demo.cpp"
	}

	filter "system:windows"
		systemversion "latest"
	

	filter "system:linux"
		pic "On"
		systemversion "latest"
		cppdialect "C++17"

	filter "configurations:Debug"
		runtime "Debug"
		symbols "on"

	filter "configurations:Release"
		runtime "Release"
		optimize "on"

    filter "configurations:Dist"
		runtime "Release"
		optimize "on"
        symbols "off"

之后点击重构

修改宏定义，把动态库的定义删除

Core.h:

cpp 复制代码 
#pragma once
//用于dll的宏
#ifdef YT_PLATFORM_WINDOWS
#if YT_DYNAMIC_LINK
		#ifdef YT_BUILD_DLL
		#define YOTO_API __declspec(dllexport) 
		#else
		#define YOTO_API __declspec(dllimport) 

		#endif // DEBUG
#else
		#define YOTO_API
#endif
#else
#error YOTO_ONLY_SUPPORT_WINDOWS
#endif // YOTO_PLATFORM_WINDOWS

#ifdef YT_DEBUG
#define YT_ENABLE_ASSERTS
#endif

#ifdef YT_ENABLE_ASSERTS
#define YT_CLIENT_ASSERT(x,...) {if(!(x)){YT_CLIENT_ERROR("断言错误：{0}",__VA_ARGS__);__debugbreak();}}
#define YT_CORE_ASSERT(x,...) {if(!(x)){YT_CORE_ERROR("断言错误：{0}",__VA_ARGS__);__debugbreak();}}
#else
#define YT_CLIENT_ASSERT(x,...)
#define YT_CORE_ASSERT(x,...)

#endif // YT_ENABLE_ASSERTS



#define BIT(x)(1<<x)
//绑定事件定义
#define YT_BIND_EVENT_FN(fn) std::bind(&fn, this, std::placeholders::_1)

imGui.Layer.cpp:强转float，把警告消除，实在找不到不改也没关系

cpp 复制代码 
io.DisplaySize = ImVec2((float)app.GetWindow().GetWidth(), (float)app.GetWindow().GetHeight());
